A delegation of Gorkha Janmukti Morcha (GJM) has called for an all party meet in Darjeeling on 13 June.
Earlier on 12 June, the Central Reserve Police Force (CRPF) said that normalcy was returning to Darjeeling, as the strength of the force has been increased to tackle the indefinite strike called by the Gorkha Janmukti Morcha for a separate Gorkhaland.
Paramilitary jawans of the CRPF and the Rapid Action Force (RAF) have been deployed in Darjeeling in large numbers.
CRPF Commanding Officer Sunil Kumar Savita told ANI that "more companies have been called in controlling the agitation in the state. Everything is getting back to normalcy and people have already started arriving at offices. We have the paramilitary forces and police officers patrolling the streets 24X7".
The officer also said that the women battalions have also been deployed to beef up the security.
However, GJM president Bimal Gurun has warned tourists asking them to leave Darjeeling immediately as "the situation is turning worse, and anything can happen".
The GJM general secretary Roshan Giri earlier sought the Centre's intervention in the political turmoil in the state.
Chief Minister Mamata Banerjee has branded the GJM protest as 'abhorrent' and appealed to the people of the region to maintain peace.
The GJM supporters are also protesting against the alleged imposition of Bengali in the schools of the hills.
The agitation arose from an announcement made by Mamata Banerjee earlier that Bengali would be taught compulsorily up to Class 10 in the state schools.
After the GJM cadres clashed with the police following their protests against Mamata's visit to Darjeeling and her decision to make Bengali compulsory in syllabus of schools across the state, the Army was called in to control the situation.
The protest led by the GJM turned violent after protesters resorted to vandalism as they torched police vehicles and attacked policemen.
