Bangkok bar fire: Victims died of cyanide poisoning within minutes, autopsies show

Victims of a fatal fire at Bangkok's Rong Beer Na Lat Phrao bar died within minutes due to cyanide poisoning, according to preliminary autopsy findings. The blaze is suspected to have been triggered by a short circuit resulting from an overloaded electrical system.

Investigators are examining the electrical system, which reportedly had an inadequate initial supply capacity that was later exceeded. Police suspect electrical work may have been performed without official inspection, potentially leading to the overload.

Adding to the tragedy, witness accounts suggest an emergency exit near the toilets was bolted shut when the fire broke out. This severely hampered evacuation efforts, as those attempting to flee had to remove the bolt first.

Authorities are awaiting final reports from forensic and engineering bodies to confirm the cause of the fire and assess compliance with safety standards. Over 106 people have been questioned, including management, employees, and officials, as the investigation continues.
