Metro services were disrupted for an hour on Sunday afternoon after a woman jumped in front of a train at Belgachhia station.

The 25-year-old survived but her left arm had to be amputated. She was first taken to RG Kar hospital from where she was shifted to a private hospital in Salt Lake. “Her left arm was amputated.... She has a fractured rib and needs multiple surgeries,” said an official of the hospital.

The suicide bid happened at 11.20am, said a Metro official. The driver of the New Garia-bound train applied the brakes but the woman still got under the train. Train services from both ends resumed after 12.20pm. The disruption left many passengers stranded.

Metro passenger count on Sunday was 19,176.
