New Delhi, Feb 24 (IANS): Baharatiya Janata Party (BJP) member of Parliament Gautam Gambhir criticised the anti CAA-activists for violence, believed to be the cause of a Delhi Police personnel's death, here on Monday.

"Extremely sad to hear about death of senior police constable Ratan Lal during violent anti-CAA stir. There is no scope for violence in democratic protests," Gambhir said and demanded action against perpetrators of violence.

"I request everyone to maintain peace and urge the Delhi Police to take strict action against culprits," he said.

On Monday, the head constable was killed as pro- and anti-CAA groups fought a pitched battle even as Lieutenant Governor Anil Baijal and Chief Minister Arvind Kejriwal appealed for peace and harmony.

A youth also received bullet injury, while several vehicles and a house in the vicinity were set ablaze.

Several areas, including Jaffrabad, Maujpur and Gokulpuri, remained tense.
