MUMBAI, June 27 -- Exactly 48 hours after a 22-year-old commuter was stabbed to death after a heated quarrel in a Nalasopara-bound local train, a 35-year-old man was left seriously injured after being knifed by a fellow pedestrian, also after a petty quarrel, outside Mahim railway station on Thursday night. Navin Prasanna had returned by local train from his workplace in Lower Parel and stepped out of Mahim station at 10:15pm, when he accidentally bumped into another pedestrian on the footpath. The accused, currently at large, claimed his mobile phone fell to the ground and broke, and demanded that Prasanna compensate him. When Prasanna refused, he whipped out a knife and allegedly stabbed him several times. "We have registered a case of attempt to murder, criminal intimidation and intentional insult with intent to provoke a breach of the peace, of the Bharatiya Nyaya Sanhita, 2023, against an unknown person," said an officer with the Mahim police. Prasanna is a resident of Pitamber Lane in Mahim west. His brother Sachin said, "My brother works as an office boy with an advertising, entertainment and technology company in Lower Parel, and was attacked outside Mahim station. He suffered serious injuries and was unconscious for 15 hours." Police said Prasanna had suffered serious injuries to his abdomen and was rushed to Sion Hospital by locals. The accused fled immediately after the stabbing. "We suspect he took a train and fled. Prima facie, he seems to be a drug addict," said the police officer, adding that they are looking for the accused....
