A four-storey residential building collapsed after catching fire in Mumbai's Kalbadevi area on Saturday.
At least 12 people, including two firemen, have been injured in the mishap.
A local Bharatiya Janata Party (BJP) MLA, Raj Purohit, informed that a fireman was still trapped inside the building.
"Two families were residing in the building and one was out for a holiday. The second family is safe. Two fire officers are seriously injured and one is still inside. We have no news of him till now. We pray to God that the fire officer comes out fine," he said.
