Chinsurah, May 27 :    Chinsurah, May 27:  A 30-year-old man, said to be a Trinamul Congress worker, was murdered on Sunday night at Konnagar in Hooghly just a day after the special task force of the district rounded up two dozen criminals who had unleashed a months-long reign of terror in the town. Police said five miscreants dragged out Mubarak Hossein, a contract labourer with the Konnagar municipality, and stabbed him. Finally, they pumped in bullets into his chest. Gang rivalry is suspected to have led to the killing. The killing came as a blow to the town's population which was hoping to return to normal life after the raids. In fact, shops and business establishments, which used to down shutters at sunset for the past five months, extended their working hours till 8 pm today. 'I have decided to set up two permanent police camps to wipe out criminal activities permanently from the area,' Hooghly superintendent of police N. Ramesh Babu said. One camp will come up near Konnagar railway station and another in the Kanaipur-Bansai area. Clashes between gangs led by Bagha and Shyamal for the past 10 months had resulted in more than 12 deaths. The kingpins have eluded the task force. Unable to lay their hands on Shyamal, the police arrested his brother-in-law, Hiranmoy Das, and associate Seikh Abdul on Saturday. Bagha was arrested seven months ago, but is out on bail. His lieutenants were, however, picked up.
