Part of a four-storey building in India's financial capital collapsed in heavy monsoon rains, killing 10 people including five members of one family, authorities today.
Rescuers used sensors and life detectors but couldn't recover anyone alive from the debris of the building in the Sion area of Mumbai, the local Municipal Corporation said.
The dead included five members of a local businessman's family and three from the family of a lawyer, it said in a statement.
Six other people were injured when the structure collapsed Monday night, said Vijayendra Dahiya, an official at the National Disaster Management Authority.
Dahiya said the cause of the collapse was not immediately known.
Police cordoned off the building fearing more of it could cave in.
Building collapses are common in India as builders try to cut corners by using substandard materials, and as multi-storey structures are built with inadequate supervision.
In April, 74 people were killed when an eight-story building being constructed illegally in the Mumbai suburb of Thane caved in. It was the worst building collapse in the country in decades.
The massive demand for housing around India's cities and pervasive corruption often result in builders adding unauthorized floors or putting up illegal buildings.
