At least six persons police personnel and and picketers were injured.

A school bus ferrying students was also attacked near Tista Bazar along National Highway 10. The students were on the way to a hospital from their hostel for routine check up.

Gurung on Thursday had warned if tripartite talks on Gorkhaland were not held immediately, the situation in the Darjeeling hills would further worsen.

“Tripartite talks have to be held as soon as possible, else the situation in the hills will deteriorate and the state government would be responsible for it,” Gurung said in an audio message from an undisclosed location.

Urging the pro-shutdown activists to further intensify the “picketing” from Friday, Gurung said the government would have to take responsibility if any untoward takes place in the hills.

Gurung’s comments came two days after the second phase of the government sponsored all-party meeting in Jalpaiguri, where West Bengal Chief Minister Mamata Banerjee agreed on a few points with the hill parties but refused to commit, stating legal issues.
