Large-scale violence and arson took place in Kurseong town in the afternoon even as Army troops remained stationed in Darjeeling, Sonada and Kalimpong.
An Army column of around 50 personnel was deployed in Kalimpong on Monday night, while two columns were sent to Darjeeling and Sonada on Saturday last week.
Official sources said the district administration has extended the ban on Internet services till July 25. The ban was imposed on June 18.
Meanwhile, the Gorkha Janmukti Morcha, the spearhead of the statehood agitation, rubbished the West Bengal government's allegation that it "has a tacit understanding with Maoists and is getting tactical support from them".
"The allegation levelled against us that we are getting support from Maoists is completely false. We challenge the state government to prove the allegation," GJM youth wing chief Prakash Gurung told reporters.
He also accused the state government and police administration of violating human rights in the hills.
Earlier in the day, GJM supporters took out a rally in the Chowkbazar area and shouted slogans in support of a separate Gorkhaland. Processions were also taken out by activists of several political parties dressed in traditional Nepali attire.
Police and security forces patrolled the streets of the hills and kept a tight vigil on every entry and exit routes.
Except pharmacies, all the other shops, restaurants, hotels, schools and colleges remained closed.
With food supply severely hit due to the shutdown, GJM activists and NGOs of the hills were seen distributing food items among the people.
