The Delhi Police are likely to charge Chief Minister Arvind Kejriwal and his deputy Manish Sisodia with criminal conspiracy in connection with the alleged assault on Chief Secretary Anshu Prakash in February, several reports said on Thursday.

The police will file a chargesheet at the Tis Hazari court either on Saturday or early next week, the Hindustan Times reported, citing an unnamed official.

Prakash has alleged that Aam Aadmi Party MLAs Prakash Jarwal and Amanatullah Khan had assaulted him at the chief minister’s residence on February 19. The two MLAs were arrested and are currently out on bail. The police have questioned 11 AAP legislators who were present when the alleged incident took place. Kejriwal and Sisodia were also present.

Though Kejriwal was not named in the FIR, the police have questioned him twice. He has denied Prakash’s allegations and claimed that the case was “politically motivated”.

The police had searched Kejriwal’s home for the closed circuit television camera footage on February 23 and said that 14 out of the 21 cameras were operational, but running behind time. There were no cameras in the room in which the alleged assault took place, the police had said.

The alleged assault had triggered a tussle between the Delhi government and its bureaucrats, leading to Kejriwal and other members of his Cabinet protesting at the home of Lieutenant Governor Anil Baijal from June 11. This was to protest against an alleged strike by IAS officers in Delhi and to urge Baijal to get them to return to work. Kejriwal’s Aam Aadmi Party also accused the Prime Minister’s Office of orchestrating the alleged strike.

The IAS officers denied that they were on strike, but said they had stopped attending meetings with ministers after the alleged assault on Prakash. The bureaucrats finally agreed to meet the chief minister after he assured them that he would ensure their safety and security “with all powers and resources available at my command”.
