Security personnel in large numbers were deployed in the hill district of West Bengal after widespread clashes between GJM activists and the police were witnessed on Saturday.
Police recovered more than 300 weapons, including arrows and explosives.
Police fired teargas shells and used batons to disperse the crowd.
While a group led by Binay Tamang wants to end the shutdown, the mainstream GJM, led by its supremo Bimal Gurung, wants the status quo to continue, reports Avishek Rakshit.
A Gorkha Janmukti Morcha supporter attempted self-immolation in Darjeeling as the indefinite bandh by the GJM for a separate Gorkhaland entered the sixth day on Thursday, even as the West Bengal government said it would follow court orders strictly to maintain normalcy.
Police earlier fired tear gas shells and lathicharged GJM supporters
Ambulance operators were refusing to carry patients due to fear of harassment.
After protests by Trinamool Congress, the Centre on Friday promised not to hold any talk with Gorkha Janmukti Morcha without involvement of the West Bengal government and said the recent meeting of the group's leaders with Home Minister Sushilkumar Shinde was "coincidental".
Protesters also burnt effigies of Banerjee and vowed to continue their fight for Gorkhaland.
Gurung is worth his weight in gold to the BJP which is trying hard to make inroads in West Bengal
Most of the coded signals and communications were in Nepali and Tibetan languages.
Gorkhaland supporters torched a police outpost, a toytrain station and clashed with the police at two places.
Pitted against Bharatiya Janata Party's S S Ahluwalia who has the backing of the Gorkha Janmukti Morcha, Trinamool Congress nominee Baichung Bhutia said the real issue in Darjeeling hills was not a separate state, but lack of development.
It was the state government which has violated human rights and slapped false cases against the GJM, he claimed.
Hurling petrol bombs and stones, Gorkhaland supporters on Thursday fought pitched battles with police, who broke up protests, bursting teargas shells and baton-charging violent crowds, plunging Darjeeling hills into deeper turmoil.
'Helpful neighbours, useful nuggets of information keep the people going as supplies run low.'
'A master politician who excelled in the politics of intrigue, Subash Ghisingh kept winning election after election, sending a clear message to the state and central governments that he remained the undisputed king of the Darjeeling hills.'
She said in such a scenario, the Centre and the state must start talking on the matter.
'The CM seems to have forgotten that she is dealing with the Gorkhas, people known for their valour and loyalty to India.' 'It is shameful that Mamata Banerjee and her administration treated them like insurgents, choosing to use live bullets instead of other ways and means to control crowds.'
'If the nub of India's sensitivity over the Chinese presence in Doklam is the enhanced threat to the Siliguri Corridor, a vital link to the northeast, does it serve the national purpose to have the districts along it, and then much of the tribal northeast, in turmoil?' asks Shekhar Gupta.
