Fourteen fire engines, one rescue van and an ambulance have been rushed to the spot. When the rescue operations were going on fire brigade officer said 30-40 persons were still feared trapped.
"The civic body's control room received a call at around 10:43 am about the accident", Brihanmumbai Municipal Corporation's (BMC) fire brigade department chief P.S. Rahangdale said. The doctors from the hospital said that they are expecting more casualties and the existing patients have suffered trauma injuries but none of them are in critical condition.
He said he escaped unhurt in the collapse as he had left for his office before the building collapsed. "Then I came out of my building and found a lot of dust, cries and noise of people seeking help". The building figured on the BMC's list of "dangerous buildings".
"The entire residential building has collapsed".
The building is thought to be 35 years old.
After visiting the spot, Congress leader and MLA Naseem Khan said prima facie BMC has failed to curb the ongoing adjustment in the building. The building houses hospital on the ground floor, which was closed for renovation and the upper three floors had apartments where 20 families resided.
Mumbai Mayor Vishwanath Mahadeshwar visited the spot and said a proper inquiry will be conducted into the incident. He added that those responsible for the tragedy "will not be spared".
Sniffer dogs are also taken to the site and were been pressed into service.
