Union Minister of State for Home Affairs Hansraj Gangaram Ahir stated this in a written reply to a question in the Lower House of Parliament.
Darjeeling has been witnessing an indefinite strike called by the Gorkha Janmukti Morcha (GJM), demanding a separate state of Gorkhaland, since June 12. Several police stations and government offices have been torched by protestors in the hill station.
"Violence and damage to public property have been reported during the agitations," said Mr Ahir.
He added that according to the Constitution, the states were primarily responsible for the maintenance of law-and order.
The Centre, on a request from a state government, provided assistance by sending Central Armed Police Forces (CAPFs) personnel, said the minister.
Similarly, CAPF battalions were provided to the West Bengal government as well for the maintenance of law-and-order in the Darjeeling hills, he added.
