One of the suspects in the rape and murder of an 11-year-old girl was killed in a police encounter last night in the Baruipur suburb of Kolkata. Around midnight, Pravash Mondal was taken to the spot for the reconstruction of the crime. During this, he tried to snatch a firearm from the police and flee, sources told NDTV. Mondal was among the three suspects arrested after the girl's body was found stuffed in a sack from a pond in Baruipur. The two others have been identified as Ananda Sardar and Dibakar Sardar. Sources said they had confessed to their crime. A fourth accused, Kabir Mollah, was picked up from Basirhat yesterday. A wave of violent protests swept the southern suburbs after the girl's body was found on Sunday, as angry locals damaged railway tracks and police vehicles.
