According to reports, a group of young men, who allegedly were supporters of BJP's prime ministerial candidate Narendra Modi, hurled stones and brickbats at Kejriwal near the Banaras Hindu University.
During this election campaign, Mr Kejriwal has been assaulted repeatedly - at least three men have hit him during his road-shows, and he has been sprayed with ink. Earlier this month, he was slapped in Delhi by an auto-rickshaw driver, whose house he then famously visited the next day.
Kejriwal was on his door-to-door campaign in Varanasi when the attack took place while he was at the famous Keshav Paan shop around 8 pm.
Keshav Chaurasia, the owner of the paan shop, has reportedly been short-listed by the BJP as one of the people who will formally propose Mr Modi as the BJP's candidate for Varanasi and accompany the politican to file his nomination papers.
Pappu, the owner of a popular tea stall at Assi, has reportedly been finalized as another proposer. Pappu's tea stall was one of the prominent venues for Mr Modi's famous 'chai pe charcha' or mass outreach programme last month.
Mr Kejriwal made it a point to include Pappu's tea stall and Keshav's paan shop in his public contact programme during which he is inviting questions and suggestions from the public.
