The death toll from a fire at Food and cigarette packaging plant near Dhaka over the weekend rose to 31 on Monday, Reuters reports.
The blaze erupted early on Saturday. The cause of the fire in the Tongi industrial zone about 20 km (12 miles) north of the capital, Dhaka, was not immediately known, but officials said a gas line leak and a boiler explosion probably triggered it.
"Police have filed a case in relation to the fire in which 31 people have so far died," said Farid Ahmed, deputy inspector general of the country's factory inspection department.
A police official said the case had been filed by the family of one of the victims. Officials expect more cases to be filed against the owner, whom police are still trying to locate, and others when courts re-open after the week-long Eid holiday.
Many fear the death toll could rise further as close to half a dozen people are still missing after the blaze caused a partial collapse of the factory building.
