Ashwanth (20) and Sojith (25) were arrested based on CCTV footage, and were produced before court.
"We evaluated the CCTV footage and identified the culprits and apprehended two of them. Ashwanth was one of the three suspects who came on a bike and attacked Naseer," an investigating officer told PTI.
