Besides Kejriwal, summonses were issued to journalist-turned-politician Ashish Khetan and AAP's Punjab affairs in-charge Sanjay Singh by Chief Judicial Magistrate Gurpartap Singh in a case filed by Punjab Revenue Minister Bikram Singh Majithia.
The development came on a day when Kejriwal visited Golden
Temple to perform volunteer service.
On May 20, Majithia had filed a criminal defamation case against the three in a court here alleging that AAP was bent upon tarnishing his and his family's image by levelling baseless allegations.
Those named as accused in the case are out on bail.
