Thai authorities said on Monday that a preliminary investigation indicated a short circuit was the likely cause of a deadly fire at a Bangkok pub that killed 27 people and injured dozens more.
According to Bangkok's Department of Disaster Prevention and Mitigation, investigators believe the blaze was triggered by an electrical short circuit in the air-conditioning system mounted to the pub's ceiling. The fire damaged about 164 square meters of the venue, while the exact cause remains under further investigation.
The fire broke out at around 23:57 local time on Sunday at the pub near Lat Phrao Road in Bangkok's Chatuchak district.
Bangkok Governor Chadchart Sittipunt said that in addition to the deaths, the fire injured 63 others, including 22 who remained in critical condition and required intubation.
Thai Prime Minister and Interior Minister Anutin Charnvirakul visited the scene early Monday to oversee rescue efforts. He said most of the victims died from smoke inhalation, while the injured had been transferred to hospitals.
Firefighters extinguished the blaze about half an hour after it erupted, but officials said the fire had already spread rapidly throughout the venue before emergency crews arrived.
Authorities have so far formally identified only a small number of the victims. Local media reported that rescue workers also recovered numerous mobile phones from the scene, many of which continued to receive calls from relatives and friends seeking information about their loved ones.
Survivors told local media that they first noticed smoke rising from an electrical distribution box near the stage before the power suddenly went out. An explosion followed, sending thick smoke through the venue and triggering panic among people trying to escape.
Many people reportedly fled toward the rear of the building, where restrooms were located, but witnesses said there was no clearly marked exit in that area.
Thai media reported that the venue was licensed as a restaurant with live music performances and had two emergency exits. Authorities are also investigating whether either exit was accessible when the fire broke out.
