Social media was abuzz with pictures of the car which forced the party to issue a clarification saying the car belonged to a party volunteer.
"The Scorpio in question belongs to a volunteer. We have already shown ownership papers. The car was delivered to him yesterday. It had nothing to do with Rakhi," AAP spokesperson Deepak Bajpai said.
Meanwhile, a group of people carrying placards had turned up in front of the venue at Mangolpuri alleging that Jha, an invitee at the celebrations, was shielding a murder accused.
The party claimed when the protesters tried to "barge" their way into the celebrations a minor scuffle ensued.
"Jha had launched a campaign against gambling in his constituency because of which several anti-social elements were affected. The so-called protest was a result of his proactiveness," Bajpai added.
