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.
"Why are all the attacks taking place only on us?" Kejriwal asked. "There will be more attacks, and we can also get killed."
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.
