A 21-year-old man sustained serious injuries after he was allegedly pushed out of a running train when the ticket checker found that he was travelling — on a local passenger train going from Bhilad to Vapi in Valsad — without a ticket, said police on Thursday. The Vapi GRP Police has registered a case against the accused, Ashok Kumbhare, and started a probe. According to police sources, victim Sandeep Arya, and Ajay Kumar, who work at a factory in Vapi, had gone to Bhilad to buy some parts required for repairing a boiler. On Tuesday night, when the duo reached Bhilad railway station, they found that the Mumbai-Valsad local train was about to leave and boarded the train without buying a ticket, said police sources. On the way, the ticket checker caught them travelling without a ticket following which he asked them to pay Rs 1,000 each as penalty, to which they refused, leading to heated arguments between them. The duo also made Kumbhare talk to their firm owner, Sarfaraz Malavikya, but the former was not convinced, said police. Later, Kumbhare allegedly took away Arya’s mobile phone as he was trying to reach out to other people. When the train arrived at Vapi station, both attempted to get down but were stopped by Kumbhare, who told them to accompany him to Valsad railway station to be handed over to the Railway Protection Force. Both started arguing with Kumbhare, angered by which he allegedly pushed Arya from the running train at Balitha railway crossing, said sources. Ajay immediately pulled the emergency chain and reached the spot where Arya was lying severely injured, following which he was taken to Valsad Civil Hospital, said police. Sandeep is undergoing treatment in the ICU ward and his condition is said to be critical. The Vapi GRP has registered a case under the Bharatiya Nyaya Sanhita Sections 110 (attempting to commit culpable homicide) and 352 (intentional insult with the intent to provoke a breach of peace) against the accused.
