Three people, including a 12-year-old boy, were killed and three others injured after a speeding Cluster Scheme bus lost control on a flyover in northeast Delhi’s Nand Nagri late on Thursday night. The bus rammed into several vehicles and street vendors before coming to a stop. Angry local residents pelted stones at the bus and broke its windows. Police received a call about the accident around 10pm on Thursday. Eyewitnesses told the cops that the Cluster bus was coming down the ITI flyover near Nand Nagri when it seemed to be out of control. Two of the three men who died in the accident have been identified as Ravinder (22) and Karan (12). The identity of the third, aged around 40, is yet to be established.
