Official sources said that the directions were issued following intelligence inputs which suggested that Rampal's followers were planning to travel to Delhi for a dharna at Jantar Mantar in support of the Satlok Ashram chief.
Security personnel, including traffic and general police, have been directed to screen all vehicles, including private cars and buses, state-owned buses of various states like Haryana, Punjab, Himachal Pradesh and Chandigarh and goods-carrying vehicles headed for Delhi, sources said.
Persons suspected to be followers of Satlok Ashram have been asked to be taken off the vehicles. These persons are to be detained till further instructions and let off only after proper verification, the sources said.
