On August 3, 2026, officials from Mueang Kanchanaburi district administration, the Kanchanaburi provincial military security command, the 9th Infantry Regiment intelligence unit, Border Patrol Police Unit 13, and Mueang Kanchanaburi police station conducted a raid on a rented raft positioned near Koh Kaew in the middle of the Mae Nam Khwae Noi River in Nong Hya subdistrict, Mueang district, Kanchanaburi province. The operation followed a tip from a concerned citizen that dozens of teenagers had rented the raft to host a drug-fueled party.

During the raid, officers discovered more than 50 male and female teenagers drinking and partying on the raft, with some showing signs of drug intoxication. A search recovered ecstasy and ketamine from four male teenagers. Subsequent urine tests on all teenagers present revealed that 14 male teenagers and 21 female teenagers tested positive for drug metabolites (indicated by purple-colored urine). All 35 positive cases were taken into custody for legal proceedings.

Later, the raft was relocated to a proper dock at Ban Linthang, where Deputy Governor Wuthiphong Suphakvanitchaya inspected the scene personally. Officials also questioned the raft owner, who claimed the teenagers had rented the vessel normally for a birthday party and denied knowledge of any drug-related activities.

At 11:15 p.m. on August 3, police and rescue workers from Phatthalung responded to a single-vehicle crash on Asia Road in Don Thai subdistrict, Khuan Kanung district, Phatthalung province. The Toyota pickup had collided hard with a tree, with the front end severely damaged. The cargo gate gave way, scattering fresh vegetables across the road.

Inside the vehicle, 32-year-old Nupol was pinned in the cabin, his lower body trapped against the steering wheel. Rescue personnel used cutting equipment to free him over approximately 15 minutes. He suffered severe facial lacerations and was conscious but critically injured, and was rushed to Khuan Kanung Hospital.

According to Nupol's traveling companion, who was following in another vehicle from Ratchaburi, they had been in phone contact throughout the journey. The driver was transporting fresh vegetables to a customer in Pattani province. The companion reported hearing prolonged brake sounds just before the truck suddenly veered left and hit the tree hard. It is suspected that another vehicle may have cut in front suddenly, forcing Nupol to swerve and causing the crash.

The Pheu Thai Party has clarified the facts in a case involving former member Thisanee Chunhawan, who publicly alleged she was sexually harassed by a Move Forward parliamentarian but was silenced by the party to protect its image. The party's statement explains that party executives were made aware when Thisanee disclosed the incident to Picharn Chaowpattanawong, then Move Forward's deputy leader, who reported it to party secretary Chaitawat Tulathon as a serious matter warranting investigation and disciplinary action. However, Thisanee at that time stated she only wanted to inform Picharn of what happened but did not want the party to take any action and refused to reveal the alleged perpetrator's name. Because Thisanee would not disclose the name, Move Forward could not proceed with a full investigation. Party executives from both Move Forward and Pheu Thai deny ever requesting Thisanee's silence to protect the organization's image, noting that other cases have been investigated and perpetrators punished publicly. The party states it has never closed the door on investigating Thisanee's case and is willing to proceed fully if she now consents, having already begun inviting her and relevant witnesses to provide information. The party firmly emphasizes that sexual harassment is a serious offense, rejects any culture of protecting wrongdoers, and is prepared to impose appropriate penalties while considering the full impact on the victim.

On August 3, 2025, officers from the Eastern Command and the Aranyaprathet Task Force, including troops from the 12th Royal Forest Department Control Unit and the 2nd Information Operations Team, conducted a patrol to prevent illegal border crossings in Aranyaprathet district, Sa Kaeo province. During their patrol near Ban Pa Rai Mai village, officials spotted a group moving suspiciously through a natural passage and detained three Cambodian nationals—two men and one woman—who had no passports or legal entry documents.

During interrogation, the detainees revealed they were friends from Phnom Penh who had been recruited by an unknown Cambodian acquaintance to work sewing bags at a salt market factory. They were offered 9,000 baht per month with a Thai employer covering the 6,500-baht border crossing cost, payable upon arrival in Thailand. The three hired a tuk-tuk to take them to the border, where two unnamed Cambodian guides smuggled them across through a natural pathway.

However, as the group crossed Highway 3446, border patrol officers spotted and apprehended all three. The two Cambodian smugglers saw the officials approaching and fled back into Cambodia. The three detainees have been handed over to Khlong Luek police station for legal proceedings, while authorities continue investigating those involved in recruiting and trafficking workers across the border.

On August 3, Chiang Mai immigration police, together with labor inspectors from Region 5, conducted a sweep at a market in Mae Hia sub-district, Muang district, Chiang Mai, after receiving a complaint about illegal foreign workers. Officers arrested one Laotian woman on charges of working without a valid work permit despite holding temporary residence status, and for failing to report her employer details to the labor registrar within 15 days of starting work. Document checks revealed the woman had previously held a legitimate work permit with a Thai employer but had since illegally entered Thailand to work as an unlicensed operator selling stewed duck, competing unfairly with Thai workers. The suspect admitted to working at the stall for approximately three years without any legal work authorization. Authorities have detained the woman and referred her case to Muang Chiang Mai Police Station for further legal proceedings.
