Delhi Police on Friday visited Chief Minister Arvind Kejriwal's residence to look for evidence in connection with an alleged assault on Chief Secretary Anshu Prakash there by two AAP legislators just days back.

Additional Deputy Commissioner of Police Harendra Kumar Singh told IANS that "the raid has just begun" and police would be looking for CCTV footages besides questioning staff regarding the alleged assault.

On Tuesday, Prakash had alleged that he was beaten up by Amanatullah Khan and Prakash Jarwal -- Aaam Aadmi Party MLAs -- in the presence of Kejriwal at the latter's residence on Monday night.

Prakash was summoned there to attend an emergency meeting.
