Mohali, July 15 -- A security guard posted at Sigma City 2 in Zirakpur was allegedly assaulted by a group of five men after he questioned them for entering the society complex without making an entry in the gate register. The incident took place late on Sunday night when the duo returned and found the gate closed. According to the victim, Prem Singh, he signalled the men, who were riding two bikes, to stop while entering the society gate, but they ignored him. When they came back and were asked why they didn't stop, they dragged him aside and thrashed him, Singh alleged. He was taken to GMCH, Chandigarh, for treatment. Police lodged an FIR against Lucky and Mahik, along with their three unidentified accomplices.HTC...
