Police Probe Closed-Time Bar Permit in Deadly Fire Case
Autopsy results revealed the fire victims died from inhaling carbon monoxide and hydrogen cyanide, likely from burning foam insulation, while police investigate whether they illegally allowed the bar to operate past closing time.
On July 17, Deputy Police Commissioner Siam Bunsawat disclosed new findings in the Ladprao beer hall fire investigation. Autopsy results showed the deceased had high concentrations of carbon monoxide (CO) and hydrogen cyanide (HCN) in their blood. When combined, these gases cause severe oxygen deprivation; continuous exposure for just four minutes can be fatal. The victim inhaled these toxins rather than ingesting them, leading to asphyxiation. Scientists are still determining which material in the building burned to produce these specific poisons, with initial suspicion falling on foam insulation.
Officers who entered the building to rescue victims were also found to carry the same toxic substances in their bodies, which affected their breathing during the rescue operation. Regarding accusations that police negligently permitted the restaurant to operate beyond legal closing hours—potentially contributing to the disaster—Division 2 has formed a committee to investigate whether officers failed in their duties. The results of the inquiry will determine whether any misconduct occurred.
