"An indefinite bandh of the government and Gorkhaland Territorial Administration (GTA) offices has been called. The movement for Gorkhaland will be intensified," he said.
Gurung also said he would resign from the post of GTA chief executive shortly.
He, however, added that the GJM MLAs will not resign from the West Bengal Assembly.
Gurung cautioned the tourists saying they should stay away from the hill station as they might be inconvenienced due to the ongoing political unrest there.
State Tourism Minister Gautam Deb slammed the GJM chief for his statement.
"Darjeeling is not a property of anybody. He (Gurung) should not make such statements. No one is above the law," he said.
