Two people were killed and one injured when an empty gas tanker exploded suddenly in a garage here on Tuesday, officials said.
The incident took place at Chembur in north-east Mumbai.
According to the BMC Disaster Control, some maintenance and welding work was underway on the tanker.
Some residual gas trapped in the tanker may have been ignited by the welding flames and is believed to have caused the huge explosion.
Two people, including an 18-year old garage hand Shafiq Shaikh and another 45-year-old unidentified person, a vehicle cleaner, were killed in the blast.
A bystander was seriously injured and has been rushed to a local hospital, officials said.
There was no fire or damage to any building in the vicinity though an overhead powerline of Tata Power was broken.
