Mumbai, A retired schoolteacher was killed when a portion of a 4-storied building crashed in south Mumbai's congested Dongri area, BMC Disaster Control said on Wednesday.

Mumtaz Sudhanwala, 65, a former schoolteacher who lived alone, died due to suffocation after being trapped several hours in rubble.

The building, Razak Chamber B-Block, was a MHADA cessed building and the fire brigade said that orders were given to vacate it owing to its rickety condition.

After some residents felt the building shake late on Tuesday, many of them had vacated it as a precautionary measure, except Sudhanwala who did not move out.

Local MLA Amin Patel and MP Arvind Sawant, along with senior officials from the BMC B-Ward were present at the site to supervise the rescue and relief operations.
