Concrete chaos: Maniac hurls slab from Bangkok’s Bang Na bridge
CCTV footage reveals targeted attack as hunt begins for overpass assailant

The Expressway Authority of Thailand (EXAT) has confirmed that a chunk of concrete that shattered a car’s windscreen earlier this week was deliberately thrown from a pedestrian overpass – and not a result of any structural failure.
The shocking incident unfolded on Tuesday, April 29, on Bang Na-Trat Road, prompting immediate fears that debris had fallen from the Burapha Withi Expressway, also known as the Bang Na Expressway. However, those fears have been firmly put to rest.
EXAT dispatched an engineering team to inspect the entire area following reports that a “concrete-like object” had smashed into a passing vehicle. In a statement released yesterday, May 2, the agency said there was no sign of structural damage or spalling on the expressway.
Instead, CCTV footage told a very different story.
According to EXAT, security camera recordings captured a person deliberately throwing the object from a pedestrian bridge directly onto the road below, striking the vehicle as it passed beneath.
“This was not due to infrastructure failure,” EXAT clarified. “It was the result of a reckless and dangerous act by an individual.”
The footage has now been handed over to local police, and efforts are underway to identify and arrest the culprit. EXAT has pledged full cooperation with law enforcement to ensure the perpetrator faces legal consequences.
No injuries were reported in the incident, but the attack has raised serious concerns over pedestrian overpass safety and the vulnerability of motorists to random acts of violence, reported The Nation.
Police urge the public to be vigilant and to report any suspicious activity or similar incidents.
“If you witness anything unusual, please call the EXAT Call Center immediately at 1543. Timely reports help us act quickly and ensure justice is served.”
The incident serves as a chilling reminder of the risks posed not just by road conditions, but by people with dangerous intent.
