Panic broke out after an MGL pipeline running under an Andheri East road was allegedly damaged by an excavator during unauthorised digging soon after Saturday midnight. Three motorists were injured, two of whom are critical, and multiple vehicles were gutted. An eyewitness who lives in the area said two excavators were digging up the road near Sher-e-Punjab Society when one of them hit the gas line. An MGL official said the road digging work was not authorised and the gas supply was restored by Sunday afternoon following repairs. An FIR has been lodged against the contractor and the earthmover operator for negligence, an ACP (Andheri division) Dr Shashikant Bhosale said. The road wears a busy look during the day but sees relatively less traffic late at night. A fire brigade official said MGL quickly disconnected theGas supply, and fire personnel contained the blaze and extinguished it in an hour. The fire also damaged cables and traffic signals.
