An official at the Delhi chief minister's office said that during a telephonic conversation, Mr Kejriwal told Ms Mufti that in the national capital, law and order, and police directly come under Union Home Minister Rajnath Singh.
Mr Kejriwal assured Ms Mufti that he would convey her concern to the Union Home Minister.
The Delhi chief minister told her that he would write to Lt Governor Anil Baijal, who is in-charge of police, to ensure safety of Kashmiris in Delhi.
However, sources in the CMO expressed "surprise" at the phone call, saying Ms Mufti's PDP is an ally of the BJP, and hence, she should have directly conveyed her concern to Singh.
The victims, including four women, were allegedly surrounded and beaten up by a mob of 30-40 people.
The victims alleged that they were targeted because they were Kashmiris.
