Now GJM talks of a 'revolution' in Darjeeling hills

"There will be a revolution in the hills," he said.

"The people of Gorkhaland must be ready for intense agitation from the 20th October," he posted on Facebook.

"The Centre and the State government must respect the democratic agitation done by the people of the Hills and Dooars for Gorkhaland."

He said the GJM would not go for "bilateral talks", but tri-partite discussions.

"We also understand that the Gorkhaland issue can be solved only through dialogue," he said.

The Mamata Bannerjee government in the state has been cracking down on the GJM by arresting its leaders, sympathizers and fund-givers since the outfit stepped up the movement late July after the centre gave the go-ahead to Telangana.
