Kolkata, Aug 13 - The West Bengal government Thursday held a high-level meeting with senior police officers to prepare a roadmap for carrying out further joint operations in trouble-torn Lalgarh, a top official said.

'We held talks with senior police and district officials on how to conduct the Lalgarh operation in the coming days. We discussed the modus operandi of the joint forces and how to resolve the security problem in this Maoist-affected region,' state Home Secretary Ardhendu Sen told reporters after emerging out of the meeting in West Midnapore district.

He said the state government would also appeal to the centre not to withdraw the central paramilitary forces from Lalgarh after Sep 4.
