"We have three-point demands: Central and state forces must be withdrawn from the entire jangalmahal; the state government must officially apologise to the tribals for its torture and misbehaviour and it should immediately put an end to police atrocities," he added.

The security forces planned to set up base camps at Goaltore, Salboni and Jhargram, besides in Pirakata, he said.

A team from the Kolkata police led by Joint Commissioner of Police Ranbir Kumar reached Jhargram to oversee law and order there as the people fleeing Lalgarh would head for the town.

Another helicopter has been sought for evacuating injured security personnel to hospitals.
