With this, the total number of arrests has gone up to 10.

The attack took place when a team led by Panrui police station chief Prasenjit Dutta raided a block health centre in the area where crude bombs were stored.
Despite being attacked with bombs, sticks and bricks, police seized several plastic drums full of crude bombs and several muskets from the health centre.
The attack came over a month after workers of the ruling Trinamool Congress allegedly roughed up an officer inside the Bolpur police station in the district.
The attack on the police team has acquired political colour with the Bharatiya Janata Party and the Trinamool accusing each other for the incident.
