Calcutta, Jan. 17 :    Calcutta, Jan. 17:  A clash between criminals near the slums of Panchanantala and Kankulia, off Gol Park, in south Calcutta, resulted in the death of a goon, Nepal Mondal. The incident occurred around 3 pm. Police said Gopal Das, a local criminal, sent his men to 'eliminate' Bapi Haldar, who had been trying to extend his area of operations to Kankulia, Panchanantala and parts of Jadavpur. Das and Haldar had been on a collision course over turf rights. Failing to locate Haldar, Das' men swooped on a group playing cards in the area. 'They hurled bombs and showered bullets at Haldar's men, before they could react,' said an officer of Lake police station. Haldar could not be traced in the area till late on Thursday, the police added. Mondal, 25, died on the spot after receiving bullet and bomb splinter injuries. Four others, injured in the clash, were taken to nearby hospitals in a critical condition. 'One of them is in bad shape, having taken a blast on his chest,' said an officer. In the wake of the incident, shop-owners downed shutters and residents deserted the streets. Deputy commissioner of police (South) Kuldeep Singh, who was supervising security at Eden Gardens, rushed to Kankulia Road with a large force. 'We have rounded up seven people, but are now looking for the main culprits - Das and Haldar. More arrests will follow,' said Singh. A police picket has been posted in the area. Preliminary investigations revealed that the Das-Haldar rivalry became more acute after the former was released from jail. Das is facing murder charges. 'Haldar was trying to operate country liquor and satta dens in the area, which Das wanted to destroy. Das had been trying to eliminate Haldar for a long time,' said a police officer. Inheritance order revoked: Pressure from Trinamul Congress chairperson Mamata Banerjee has forced mayor Subrata Mukherjee to revoke the Calcutta Municipal Corporation's (CMC) circular denying inheritance rights to the stall-owners in 23 civic markets. In a revised order, the CMC is likely to allow inheritance of a stall by the wife of a dead stall-owner and for a period of five years thereafter to other legal heirs.
