Authorities have identified the cause of the road collapse near the Fai Chae intersection on Charoen Sanitwong Street as an old canal beneath the surface, combined with heavy rain and truck traffic. Multiple agencies rushed to inspect and repair the area after the incident disrupted traffic on this critical Thonburi route. At 4 p.m. on May 9th, Deputy Bangkok Governor Vishnu Saemphon visited the site and announced that repair crews and engineers were mobilized to fix the collapsed section, with completion targeted for that evening to restore normal traffic flow.

Since the road serves as a major route connecting multiple areas including Buddhhamonthon Lane, Tha Phra intersection, and Wang Lang-Siriraj, delays in repairs risked severe traffic congestion. Traffic police coordinated partial road closures and temporary tunnel diversions until the area could be cleared and repairs completed.

Daw Sithigulmanit, project supervisor for the water tunnel, revealed that the area was originally an old canal with an existing bridge. Although elevated railway construction had been completed in the area, the underlying soil along the old canal remained intact clay. This clay gradually eroded, creating cavities along the canal route. Currently, a siphon pipe is being installed beneath the tunnel, requiring excavation to 12-15 meters depth using 2.5-meter diameter piping, with directional boring coming from the opposite side.

When asked whether the soil had entirely disappeared from the old canal area, Daw explained that the original canal fill may not have been sufficiently compacted. The underlying clay soil experienced movement over time, creating cavities along the canal line. While the opposite side had been completed, this side's boring had just reached this point. Cavities had been detected and preparations were underway to drill and inject concrete to fill the voids, but heavy rain combined with heavy truck traffic caused the road to collapse before this work could be completed.

Daw noted that around 1 p.m., unusual road surface conditions appeared after the first vehicle passed. By 2 p.m., when a second heavy trailer truck passed, the road suddenly gave way. The team aimed to clear the area and complete preliminary repairs by night to restore normal traffic flow. Currently, coordination is underway to plan repairs for full restoration of the road.

Khlong Prem Prison was packed with crowds on the morning of May 11 to welcome former Prime Minister Thaksin Shinawatra's release after eight months in custody. He returned to his Chan Som Hla residence having satisfied two-thirds of his sentence requirement. Thaksin's family, close associates, and red-shirt supporters from across the country gathered to show their support for the former premier, beloved by grassroots loyalists. Reports suggest he made brief appearances to thank those who came to greet him. His political movements will remain cautious and low-key going forward, as he must continue monitoring requirements with an electronic ankle monitor for another four months and requires permission to travel. While there is no explicit ban on political expression, observers believe Thaksin will maintain a low profile for at least the next four months until his sentence is fully completed on September 9. Adding to his challenges, Thaksin faces an Article 112 lèse-majesté case stemming from an interview with South Korean media that remains under appeal. Although the lower court dismissed the charges, ruling the statements did not constitute insult to the monarchy, the Attorney General's office appealed despite its own committee recommending against it, creating ongoing uncertainty. For the next four months until his full release, Thaksin will need to remain vigilant. This appears consistent with a long-term strategy of staying hidden and waiting for opportunities. Meanwhile, critics caution that red-shirt gatherings should remain peaceful and low-key to avoid inflaming political tensions. Significantly, Pheu Thai is currently a coalition partner in the government led by Bhum Jai Thai, serving alongside Prime Minister Anutin Charnvirakul's administration, making any radical political moves inadvisable. The relationship between Thaksin, the red-shirts, and Pheu Thai is undeniably interconnected. With Pheu Thai's new leader Dr. Yasothorn Wongsawadi performing well in government without needing to weather economic storms, the party appears to be accumulating strength while waiting for the right moment. Overall, the May 11 atmosphere is expected to be lively but not volatile—relatively smooth and orderly.

At 2 p.m. on May 9, 2026, at Na Jomtien Police Station in Chachoengsao Province, Police Commander General Kittiratch Panphetch, along with Chachoengsao Provincial Governor Narish Niramaivangsma and security officials, oversaw the arrest of a Chinese national suspected of concealing military weapons and C-4 explosives in Huai Yai, Banglamung District. The Police Commander ordered a comprehensive investigation across all dimensions, citing the serious national security threat and public safety concerns.

General Kittiratch commended Senior Sergeant Major Nilpat Tongyod, commander of the mobile unit at Na Jomtien Police Station, and detectives from Nong Prueio Police Station for their alertness in spotting a gun magazine in the suspect's vehicle, which led to the search warrant and discovery of numerous firearms and explosives in a residential area.

The investigation will focus on five key areas: the suspect's background and history; entry and exit records from the country; occupation and associations; the origin, source, and purpose of the weapons; and telephone and financial transaction records. The Police Commander instructed a thorough investigation following strict legal procedures, coordinating with regional police units, immigration police, security forces, and special operations units to determine the suspect's true motives.

General Kittiratch ordered special surveillance of foreign nationals exhibiting suspicious behavior in tourist areas including Chachoengsao, Pattaya, Koh Samui, Surat Thani, Phang Nga, and Pai District in Mae Hong Son Province. Regarding the semi-automatic pistol found on the suspect during the traffic accident, investigation revealed it belonged to Sai Yai Police Station before being sold through unofficial police channels multiple times until it reached the Chinese suspect. The police officer involved is under investigation. The Police Commander acknowledged that some officers face financial difficulties leading to weapon sales, though the firearms were legally purchased and not police welfare weapons. Any misconduct will result in strict legal action.

General Kittiratch confirmed that while no evidence currently links the case to sabotage or data theft, the investigation will intensify as a precautionary security operation launched at the beginning of 2026 to scan and monitor nationwide threats. Regarding footage of the suspect practicing with weapons alongside what appears to be a Cambodian national, the Police Commander stated that while they have observed this, they are investigating whether the training relates to planning attacks or terrorist activities in Thailand, and will pursue all available intelligence.

The Anuthin government cabinet has approved and confirmed 31 pending draft laws to move forward with the new parliament, but it's particularly disappointing that none includes the Article 256 constitutional amendment draft, which serves as the first step toward drafting a new constitution. This forces the parliamentary process to restart from zero, despite over 20 million voters approving a new constitution in the referendum held alongside the 2025 elections. Prime Minister Anuthin, known for his "say it and do it" campaign slogan, previously stated that the referendum mandate for a new constitution was urgent. Yet his 19-page policy statement to parliament contains no constitutional amendment policy whatsoever, raising doubts about how sincere his repeated claims to obey the people's will and serve them as the master truly are. What exactly is he doing? Although officials claim that urgent priorities are addressing cost-of-living and economic problems first, this effectively signals that the government considers constitutional reform less important—a decision that will leave us trapped in this flawed system. We'll continue to have independent organizations that can't investigate anything and can make bewildering rulings in countless cases—from a mother's ring, to a friend's watch, to proposals to amend laws in parliament. We have National Anti-Corruption Commission members accused of accepting gold bribes from the police chief who still perform their duties as if nothing happened. We have a bizarre election system that somehow becomes transparent and pure, with no one able to question it. We have strict ethics codes applied selectively—strict for some, lenient for others—while ordinary citizens can only watch helplessly. This is what a government born from elections chose to tell us remains unimportant. Every citizen must remember this is how things really are. Checkmate.

Authorities are intensifying interrogation of a shooting instructor and navy officer suspected of supplying M4 rifles to Chinese nationals at approximately 200,000 baht per unit, following the discovery of military weapons and C4 explosives in Huai Yai, Banglamung district, Chachoengsao province on May 9, 2026. Police have detained Khachon, a shooting instructor, and Pol. Lt. Cmdr. Methee, a navy officer, for additional questioning after discovering their involvement in procuring weapons for a Chinese suspect. Preliminary investigation reveals that Khachon purchased the rifles from Pol. Lt. Cmdr. Methee Naramoy of the Royal Thai Navy for 200,000 baht. Police are currently investigating financial transactions, communications, and connections between all involved parties at Najomtien Police Station to determine whether there is an organized weapons smuggling network operating in the area.

At 4 p.m. on May 9, 2025, Bangkok Deputy Governor Vishnu Saipharunpol and Department of Public Works officials inspected the site of the road collapse occurring during construction of a drainage system and siphon pipe for the Sai Fai intersection underpass project. The contractor, Kamphaengphet Vivattana Construction Company Limited, is investigating the cause of the 5-meter stretch of severe subsidence that injured one motorcycle rider.

Prof. Dr. Amorn Pimmanmas, chairman of the Structural Engineers Association of Thailand and faculty member of the engineering department, analyzed photos showing subsidence in a single lane with the road cracking in a V-shape. This indicates loss of soil base support rather than surface pavement damage. He identified four possible causes: 1) Underground pipes or utility vaults such as electrical conduit junction boxes may have leaked at connection points, allowing soil to flow into the vaults; 2) recent rainfall may have softened the soil, making it more susceptible to flow; 3) nearby construction work involving excavation or ground exposure could allow soil movement; and 4) broken water or drainage pipes allowing water to wash away soil.

Relevant agencies must inspect underground utilities in the area. While this collapse appears less severe than the recent Vajira Hospital road collapse, which occurred near the underground railway construction, authorities should monitor for further expansion, particularly during rainy seasons when saturated soil flows more easily. Officials should use underground scanning equipment to check for cavities at regular intervals, as even small voids can pose hazards to drivers.
