AAP leader Arvind Kejriwal was Friday attacked while campaigning here for the Lok Sabha election.
Aam Aadmi Party supporters pounced on the unknown attacker and roughed him up before he was taken to a nearby police station.
Kejriwal said later that he was punched while he was seeking votes for the AAP in south Delhi's Dakshinpuri area.
The former Delhi chief minister urged his supporters not to retaliate violently.
"We are fighting for truth and honesty... Let them (our critics) attack us. We should not hit back," he said.
