KOLKATA: A first-year student of Bhowanipore Education Society College jumped from a running train and got hold of a thief who had snatched her smartphone at Akra railway station in South 24 Parganas on Sunday morning.Bruised and bleeding from her head, the gutsy 19-year-old held on to the snatcher's shirt, lying on the edge of the platform as fellow passengers caught the accused, Shamim Molla (20), and handed him over to police. The student, Komal Parida, was taken to a local nursing home from where she was referred to a city hospital that specializes in neurosurgery.Police said Parida, a resident of Maheshtala, was supposed to get down at Nungi station that comes after Akra and was standing near the gate of a ladies' compartment when the accused snatched her phone around noon. “The accused boarded the train moments after it started from Akra. As it gained pace, the youth snatched the phone and jumped on the platform. The girl also jumped on the platform and caught him. Even though she was bleeding, she did not leave him,“ said Munni Bibi, a fruit seller at the station who witnessed the incident.The phone screen broke but it was still working as Komal's mother called her when one of the passengers informed her about the incident. Ko mal was unconscious when her parents reached the station and took her to a nursing home. Her wound was stitched and a CT scan was conducted that showed a mild internal bleeding. The family immediately drove her to Institute of Neurosciences Kolkata in Mullickbazar. “The wound has been stitched and there is a mild internal bleeding from her ears. But her condition is stable and she is now kept under observation. She is not speaking much though,“ said an attending doctor at the emergency ward.Komal's kin said she was returning home from a Chartered Accountancy tuition near Rabindra Sarobar Metro station and took the Budge Budge-bound local train from Tollygunge. Her father works at a multinational company and her mother is a homemaker. The family, however, felt she fell off the train. “She is not the kind who would risk her life for a phone. She must have lost her balance when the miscreant snatched her phone and fell accidentally . We want punishment for the accused,“ said Ravi Chowdhry, Komal's uncle.Police have arrested the youth and started a case of snatching and act leading to grievous injury.
