A five-storey residential building collapsed in Mumbai at daybreak on Friday in the latest accident in India's financial capital, with dozens feared trapped inside.
Crowds formed around the rubble of the completely flattened block, owned by the city's civic administrative body the Brihanmumbai Municipal Corporation, in the east of the city.
"My son is inside. I'm waiting for them to get him out," distraught 62-year-old retiree Mithi Solakani told AFP at the scene.
Local people estimated between 40-60 people lived in the destroyed building, but BMC official Manisha Mahiskar and police said they believed some 20-24 were still trapped in the debris.
Seven people had been pulled out alive, Mahiskar said.
Five other apartment blocks have collapsed in or close to Mumbai in recent months, including one in April that killed 74 people.
They have highlighted poor quality construction and violations of the building code, caused by massive demand for housing and endemic corruption.
