The Brihanmumbai Electricity Supply and Transport (BEST) undertaking's inquiry report of the May 3 Goregaon bus fire has come out with unlikely suspects though it states that the pressure gauge of the bus's CNG tank burst, which is considered to be a very rare instance. However, BEST chairman Anil Patankar has said he wants black boxes and panic buttons on buses to warn passengers of such incidents.

Explaining the cause of the fire, the report said such incidents could happen even due to a small spark in the vicinity. "The bus's tank was full and it had completed just one trip. Sparks from food vendors, cigarette butts, hot silencers or even mobile phones can aggravate such fires, and in this case it was a jalebi vendor in the vicinity," said A S Lad, chief works manager.
