MUMBAI, Nov. 22 -- A 65-year-old retired loco pilot from Vikhroli was allegedly killed by a 19-year-old man in a brutal attack just steps away from Ghatkopar Railway Station on Thursday night. According to the police, the incident occurred when the victim, Surendra Pachadkar, a former Central Railway employee and resident of Vikhroli's Parksite area, was on his routine evening walk and was attacked around 9:30 pm near CGS Colony, 100 metres away from Ghatkopar Railway Station. He was struck repeatedly on the head with an iron rod. "A resident of the colony, Neelabai Shinde, witnessed the assault and shouted at the attacker, who then fled. Some passersby rushed him to Zynova Shalby Hospital, where he died while undergoing treatment," said a police officer, adding that a post-mortem at Rajawadi Hospital confirmed death due to severe head trauma. Pachadkar's son, Akshay reached the spot after receiving a call from his father's phone, informing him about the assault, the officer said. "Pachadkar used to go for a walk every evening from Vikhroli to Ghatkopar, and back," he added. The police initially suspected that the attacker may have been familiar with his daily route, and planned the attack. But by Friday evening, the police identified the attacker as Aman Verma, 19, and arrested him. Verma told police that he had accidentally pushed Pachadkar, which led to a fight....
