Mira Road: A 23-year-old man suffered serious head injuries after a large cement block fell on him from the elevated Metro Line 9 construction site in Kashimira on Sunday afternoon.

The incident comes a month after a safety lapse at Medetiya Nagar station of Metro Line 9, connecting Dahisar East with

Mira Bhayander, when granite stones fell into a barricaded work area, with some later puncturing the tyres of a passing school van. MMRDA had slapped a Rs 10 crore fine on the contractor, J Kumar Infraprojects Ltd, and Rs 2.5 crore on two agencies.

Sunday’s incident occurred around 1pm, when the victim, identified only as Shadab, was crossing the road. As he stopped to answer a phone call, the cement block fell on his head. Shadab reportedly lay on the road for nearly an hour as heavy vehicles parked at the spot prevented people from noticing him. He was eventually spotted by a passerby who took him to hospital in an auto.

Shadab is undergoing treatment at Wockhardt Hospital in Mira Road, said Kashimira police senior inspector Rajendra Kamble.

Local residents alleged that adequate safety measures are not being followed at the Metro construction site. They claimed that construction material, iron rods and other metal objects have fallen from the site on earlier occasions too.

There has been no official response from the contractor or the civic authorities regarding the allegations so far.
