A concrete wall collapse trapped workers in Soi Sukhumvit 66/1, Bang Na district, killing one and injuring another. A bystander revealed that just before the incident, a loud crashing sound was heard before the collapse.
At 09:50 AM on 17 July 2026, a concrete slab fell on workers at a renovation site in Soi Sukhumvit 66/1, Bang Na Nuea subdistrict, Bang Na district, Bangkok. This caused one worker to die and another to be injured. Fire and rescue teams from Phra Khanong, the Poh Teck Tung Foundation, Udomsuk police, and related agencies arrived to investigate. The deceased was identified as Mr. Zin Min Htet Aung, a Myanmar national.
Later, reporters visited the scene and found the building was two stories tall, formerly a car service center, now closed and under renovation. The collapse occurred on the second floor at the front of the building, where security personnel had erected tarps to cordon off the area.
Inside, rescue teams from multiple agencies, Udomsuk police, and forensic officers continued examining the scene. So far, no official agency has released a formal statement about the incident.
The news team spoke with Mr. Srirat, 36, the first eyewitness and rescuer. He said that at the time, he and his girlfriend were sitting in front of the building and noticed about two to three workers using tools to drill and break down the second-floor wall.
Shortly after, he heard a loud crashing noise like a large object collapsing. When he looked, he saw the second-floor wall fall onto the workers, prompting him to rush in to help immediately.
Upon arrival, he found one worker pinned under a large concrete slab covering half his body, lying motionless with blood from his nose. Another worker nearby was injured in the leg with a deep wound exposing bone, likely from flying concrete debris.
Mr. Srirat said that after the collapse, about five to six people tried to pry the concrete slab off the injured worker using metal bars but could not lift it due to its large size and estimated weight of about one ton. They had to wait for specialized equipment and officials to assist.
Witnesses also noted that the building was formerly a car service center, which closed after its lease ended and remained unused for about two to three years. A contractor recently brought workers to renovate it. The collapsed concrete was part of a long plastered second-floor wall, which fell and caused the fatality and injury.
Preliminary police investigations are gathering evidence and interviewing site supervisors, contractors, and others involved to determine the accident's cause and whether safety measures during demolition and renovation were followed. If negligence or violations are found, legal action will be taken.
