Dharamshala, March 1 -- Days after a high voltage drama between Himachal and Delhi police personnel, Bharatiya Janata Party (BJP) continued to mount its attack on the Congress government in the state accusing the state government of shielding the accused. BJP state media in-charge and MLA Randhir Sharma on Saturday said that the unprecedented confrontation between two police forces raises grave constitutional concerns and demanded a high-level probe by a central agency into the entire episode.

"When the Delhi police, armed with proper documentation and court-approved transit remand, attempted to take the accused back, Himachal police allegedly obstructed them and registered an FIR against Delhi police officials," he said. The remarks come days after a high-voltage standoff between Delhi police and Himachal Pradesh police following the detention of three Youth Congress workers from Shimla district. The incident led to political sparring in the state, with the ruling Congress terming the action illegal and the BJP defending the Delhi police operation.

The trio was arrested from a resort in Chirgaon in connection with "shirtless protest" at the AI Summit in New Delhi.
