The incident occurred as the bridge was reportedly overloaded with commuters hurrying to their homes, said the BMC Disaster Control Room.
The bridge, connecting the CSMT with the B.T. Lane near The Times of India Building and the Anjuman-e-Islam School, is used by thousands of daily commuters rushing to catch the local trains on Central Railway and the Harbour Line.
Rescue teams of the BrihanMumbai Municipal Corporation, Fire Brigade and others are at the site to help the victims.
The injured have been rushed to the St. George Hospital and Sion Hospital, said officials.
