New Delhi, April 4 (IANS): A 19-year-old man twice punched AAP leader Arvind Kejriwal here Friday while pretending to garland him as the latter campaigned for the Lok Sabha election.

“Saying he wanted to garland Kejriwal, the attacker got on to an open vehicle and punched him twice,” an Aam Aadmi Party leader who witnessed the attack told IANS.

The attacker was identified as Abdul Wahid, a resident of Delhi's Jamia Nagar area, Deputy Commissioner of Police P. Karunakaran told IANS.

AAP activists pounced on the attacker and roughed him up before police took him away.

Kejriwal was with his party's South Delhi Lok Sabha candidate Devendra Sherawat and three legislators when the attack took place 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.

In less than a month, Kejriwal has been targeted four times, including in Gujarat, Haryana and Varanasi in Uttar Pradesh.
