Calcutta, March 17 : A jeweller was shot dead at Dhangarpara in Behala last night while returning home after closing his shop. Traders today observed a 24-hour bandh in the S.N. Roy Road area where the incident took place. No one was arrested. South 24-Parganas superintendent of police A.K.Maliwal said the criminals shot Ram Chandra Mondal, 42, from close range after following him for a distance. He was rushed to MR Bangur Hospital where he was declared dead. The victim?s wife, Krishna, said Ram told her on the way to hospital that he was attacked by three teenaged boys probably hailing from nearby Banstala. The criminals had been following him in an Ambassador and asked for the Rs 20,000 they had been for long demanding from him. The murder sparked tension in the locality after residents damaged four cars, including a police van, to protest the incident. Panna Das, a local resident, said it was surprising the murder took place right under the nose of the police camp which is situated a stone?s throw away from the spot. He added that another businessman, Swapan Sapui, was murdered in the same spot a few months ago. Behala police station officer-in-charge Subir Chatterjee said such incidents can be checked if residents help them. He added that criminals take shelter in houses in the area and if police are provided information about their whereabouts by residents, they can be arrested easily. Maliwal said the gang involved in yesterday?s murder owes allegiance to Nache, a notorious criminal of the area. Sailen Dasgupta, the local borough chairman of the Calcutta Municipal Corporation, said some Behala areas have become crime-prone. ?Only identification of the criminals will not solve the problem,? he added. Run over Hirak Ghosh, an intelligence branch constable, was run over by a truck on the five-point crossing at Beleghata early this morning. He was admitted to NRS Hospital. The truck driver fled after the accident.
