Two labourers were killed after a part of an illegal structure, which was under-construction in Saki Naka, collapsed, on Tuesday morning.
The deceased have been identified as Sonu Harijan (21) and Bhandari Yadav (22).
According to the Saki Naka police, the height of the godown was being raised and an additional floor was being
constructed over the existing structure at Alwin compound.
"The pillars of floor gave away and a major part of the structure came crumbling down," said an official involved in the investigation, requesting anonymity for lack of authorisation to talk to the media.
Harijan and Yadav, who were working on the upper portion of the structure, lost their balance and fell down and were buried under the debris.
The other workers at the site immediately took them to the nearest hospital but they were declared dead before admission, the police said.
Ram Yadav (22) and Chinke Yadav (25) — two other labourers, were also injured, are currently recuperating at Paramount Hospital in Saki Naka and Rajawadi Hospital in Ghatkopar respectively.
One of the labourer who was present at the time of the incident, said, "I heard a loud noise at around 10.30 am and suddenly saw the structure coming down. I was scared and ran for my life."
"We immediately rushed for help and informed the police about the incident," one of the local resident, who refused to be named, said.
The Saki Naka police have registered a case against the owner of Alwin compound and the contractor who was handed over the structure work for causing death due to negligence, and endangering life of other workers, under the sections of the Indian Penal Code.
"Our investigations are on. We suspect that inferior quality of raw materials was being used for building the additional floor," said Senior Police Inspector S R Dhanedar of the Saki Naka police station.
