MUMBAI, May 10 -- The Government Railway Police (GRP) at the Lokmanya Tilak Terminus (LTT) on Friday arrested a 25-year-old software engineer for allegedly assaulting a ticket collector aboard the Kamayani Express. According to the complaint filed by Amit Ganesh Koli, 42, a ticket collector. The incident took place while he was checking tickets in the train. Koli said he approached a man who was standing near the doorway, and asked to see his ticket. The man, identified as Raj Kamalendra Chandrasevak Tiwari, allegedly admitted he did not have a ticket and said he had only come to drop his mother at the station. He didn't have a platform ticket either. Tiwari then allegedly told Koli that he wanted to travel to Thane with his mother and didn't buy a ticket. Koli explained to him that he will still need a ticket irrespective of the travel duration. To this, Tiwari aggressively responded, asking, "What kind of ticket is required for just 10 minutes?" He then refused to pay any fine. Tiwari's mother then arrived at the spot. When Koli explained to her that her son would have to pay a Rs.300 fine, Tiwari allegedly punched him on the head three times. Koli alerted the commercial control helpline for assistance. Tiwari allegedly continued creating a disturbance until the train reached Thane station, where Railway Protection Force constable Ramjatan Yadav boarded the train and escorted him off. Tiwari was booked by the Thane GRP and handed over to the LTT GRP for assaulting a government officer....
