Pol Col Sukthat Pumpunmuang, superintendent of Pattaya police said there investigators were exploring two possible causes of the fire: an electrical short or arson. Police banned people from entering the area as they look for forensic evidence.
The arson assumption was based on information given by a Cambodian worker who told the police that he and another three friends got in a fight with workers at another camp on Sunday night. They were suspended from work for a week by the foreman after he learned of the incident.
