Four persons were killed and 13 others injured when a fire broke out in the office of IndusInd Bank in suburban Mumbai, fire officials said.

The blaze erupted due to a short-circuit at the office of IndusInd Bank Ltd in MIDC, Andheri, at around midnight in which four of its employees died of suffocation and 13 others were injured, they said.

“Four employees of the bank died due to suffocation as they could not exit through the access door in the office,” a fire official said.

Since the ventilation area was also closed on the seventh floor, the smoke could not pass out, worsening the situation, sources said.

Eleven of the injured have been admitted to the Seven Hills hospital, while two have been admitted to the Holy Spirit hospital, officials added.
