Three persons, including a 10-year-old boy, were injured in an explosion, apparently caused by leakage of LPG from a cylinder, at a scrap shop in Mumbra area of Maharashtra's Thane city on Saturday morning, a civic official said.
Following the incident that occurred around 6 a.m. on the ground floor shop in a four-storey residential building 'Mudhal Park', its residents have been evacuated and moved to a safer place, he said.
As the cause of the blast is yet to be known, the authorities have called in the Bomb Detection and Disposal Squad (BDDS) for investigation, the official said.
