"I've committed a big mistake. I should have never done what I did. I consider him (Kejriwal) as a god," 38-year-old Lali told reporters after Kejriwal went to meet him at his residence in Kirari, west Delhi.
Lali on Tuesday slapped the former Delhi chief minister in Sultanpuri while he was campaigning for the AAP candidate in Lok Sabha poll, leaving the 45-year-old Aam Aadmi Party leader with a swollen left eye.
The attacker then denounced Kejriwal as a "liar".
"I was unhappy and wanted to meet him (Kejriwal) but couldn't. I even went to the janata darbar but failed to meet him there as well," said Lali when he was asked why did he attack Kejriwal. AAP's Rakhi Birla, who is contesting from the constituency, and party leader Manish Sisodia accompanied Kejriwal.

Kejriwal Tuesday said he faced a threat to life after being slapped. "These attacks are scripted. When they (attackers) are arrested, they repeat the (same) script," Kejriwal told the media.
The AAP chief will also be meeting 19-year-old Abdul Wahid, a resident of Delhi's Jamia Nagar area who twice punched him at a public rally April 4.
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.
