CHENNAI: Police are searching for unidentified men who kidnapped a 21-year-old youth at knifepoint since he refused to give mamool in Pallavaram on Wednesday. Sasikumar (52) of Anakaputhur owns a provisional store on Bazaar Road. His son, Lokeshwaran, would also help him by looking after the shop. Police said two days ago, 2 men visited the shop and asked Lokeshwaran for mamool. When he refused, the duo threatened to kill him and left the shop.
