According to eyewitnesses the explosion took place at the house of one Osman Gani at Bahir Signal Shankar Dewanji Hat in the city's Chandgaon area at around 12:45 am. 

Three families used to live on the second floor of the building. Gas got stranded in the house from a leakage of the pipeline, said locals.
