Chandigarh, Jan. 28 -- A robber posing as a policeman looted around Rs.14 lakh from the Chandigarh Transport Undertaking's (CTU) cash branch at the Sector 17 early Tuesday morning, despite the police post being close by. The CTU cash branch is situated on the first floor of the Sector 17 bus stand. As per the police, around 4 am, a youngster wearing a police uniform reached the branch. Seeing him in uniform, the security guard on duty, Gaurav, 23, a resident of Balongi in Mohali and a native of Uttarakhand, got scared. The accused told the guard that illegal activities were going on in the cash branch and that he had come for checking. Under pressure, Gaurav opened the door of the cash branch. Once inside, the accused began questioning him about the locker and keys. After obtaining the information, the robber locked the guard inside a room in the cash branch. He then opened the locker and fled with about Rs.14 lakh in cash. The guard kept shouting for help, but due to noise on the bus stand premises, no one heard him. Around 4.10 am, when a woman employee arrived for the next shift, she heard cries from inside. She opened the latch from outside and freed the guard. Gaurav immediately informed CTU officials, who in turn alerted the police. Police said efforts are on to identify and trace the accused....
