Police on Friday seized over 200 crude bombs and 19 firearms, apart from several rounds of live ammunition, during a special drive across the state to unearth illegal arms and ammunition.

The drive was launched at the directive of chief minister Mamata Banerjee during her visit to Bogtui near Rampurhat in Birbhum district on Thursday.

The maximum number of bombs were found at Keshpur in West Midnapore, followed by Margram in Birbhum district, where 100 and 60 bombs, respectively, were found kept hidden inside bushes.

Recovery of illegal arms and bombs was low in the Bijpur-Barrackpore belt in North 24-Parganas, where political violence was quite frequent. Till evening, only one improvised firearm was seized and three goons arrested from Jagaddal where several incidents of murders, bomb attacks and firing were reported.

The police nabbed the trio from Prabhati Sangha football ground near Shyamnagar Nehru Market.

Officials of Barrackpore Commissionerate, however, instructed police stations to accelerate raids to avoid any type of embarrassment for the state government.

Friday was the first day of the 10-day special drive undertaken by the police.
