"There is still no order for the Army to enter the campus. They are only ensuring enforcement of curfew in the area," Chahal said.
The Army along with the police and paramilitary forces has put up barricades at entry points of the Dera Sacha Sauda premises.
Chahal said that a high-level meeting between the Army and the state authorities was underway this afternoon.
Fifteen Dera followers have been arrested since last night here, police said.
"We will not spare those who have taken the law in their hands. We will take strict action against then," IG (Hisar) A S Dillo said outside the Dera headquarters.
Sources said th Army was last night provided with the map of the sprawling dera campus, which is spread over nearly 1,000 acres and is a township on its own, with schools, sports village, hospital and cinema hall.
