At least 100 residents are believed to be trapped in the debris of a five-storey building that collapsed on Monday in the south of Mumbai.
The building located in Mahad, about 165 km from the financial capital was home to nearly 200 residents.
“I believe about 100 to 125 people must have been inside at the time of its collapse,” Bharatshet Maruti Gogawale, the local lawmaker said.
Authorities have yet to ascertain the cause of the collapse and the number of casualties, but about 30 people were pulled out by rescue teams and local residents.
Images showed locals and police trying to reach the trapped people.
Maharashtra chief minister Uddhav Thackeray has assured the local administration of all possible support for speedy rescue and relief work, his office said on Twitter.
Three teams from the National Disaster Response Force have been moved to the site, the NDRF said in a statement.
Old creaky structures and illegal constructions in India often lead to collapses, typically during torrential rain.
More than 1,200 people were killed in 1,161 building collapses across India in 2017, according to latest data from the National Crime Records Bureau..
