Another 10-odd families are still believed trapped under the rubble of the Kesarbai Building in Dongri area after its rear illegal portion came crashing down around 11.30 a.m.
Those killed been identified as Sabiya Nissar Shaikh, 25, Saira Rehan Shaikh, 25, K. Amirajan, 13, Sanaa Salmani, 25, Zuber Salmani, 20, Abdul Sattar Kaloo Shaikh, 55, Muzammil Mansoor Salmani, 15, Javed Ismail, 34, Arhan Shehzad, 40, and toddler Ibrahim, 18 months, said a BMC spokesperson.
Chief Minister Devendra Fadnavis ordered a probe into the building crash and assured strict action against those found guilty.
Opposition leaders like Vijay Wadettiwar, Prithviraj Chavan, Naseem Khan, Ashok Chavan, Milind Deora (Congress), Dhananjay Munde, Majeed Memon, Jayant Patil and Nawab Malik (Nationalist Congress Party), and Abu Asim Azmi (Samajwadi Party) among others lashed out at the government for lapses leading to the tragedy.
They demanded a detailed investigation into the causes leading to the accident, identifying the culprits and booking them under charges of culpable homicide not amounting to murder.
Meanwhile, an RTI activist said that the name of the dilapidated structure, is mysteriously omitted from a comprehensive list of 499 "dangerous" buildings prepared by the BrihanMumbai Municipal Corporation (BMC).
"The BMC, as per the directions of the Bombay High Court, had compiled the list of the dilapidated buildings, which we secured through a RTI reply. Shockingly, Kesarbai Building's name is not mentioned anywhere in the list," Shakeel Ahmed Sheikh told .
Later on Tuesday evening, the Maharashtra Housing and Area Development Authority's (MHADA) chief spokesperson Vaishali Gadpale cleared the air on the building's status.
In a statement, she said that the main dilapidated structure, Kesarbai Building 25/C was completely evacuated by the MHADA last year and the building which collapsed on Tuesday "was the illegal rear portion of this building which is not within the purview of the Mumbai Building Repair & Reconstruction Board".
Earlier in the day, MBRRB Chairman Vinod Ghosalkar had said that the dilapidated structure, believed to be over 80 years old, had been handed over for redevelopment to B.S.B. Developers, which has not yet started the work.
"This is a serious matter and we shall investigate why the redevelopment work was not initiated, what caused the delays and take appropriate action against those responsible," Ghosalkar told .
Among those rescued from the debris include five women, three men and two children aged 3 years each. They are being treated at various hospitals and the two minor males were discharged after treatment.
As a precautionary measure, the police evacuated all residents of an adjoining building and shifted them to a nearby school to facilitate the relief works.
However, narrow approach roads, huge crowds and thickly populated areas, besides continuous VVIP movements to the site, affected rescue operations.
