Kejriwal, who held a rally at the city protesting against Khurshid at his own constituency, reached the venue as many protesters blocked his convoy and attacked India Against Corruption (IAC) supporters.
Situation in the city turned violent when Khurshid aides clashed with IAC members with sticks, stones. The windows of a car, which was heading towards the rally ground, were smashed.
Earlier, Khurshid had threatened Kejriwal saying, "So far I was working with a pen, but now will also work with blood...The road to Farrukhabad is long. Let him go there... we will see how he comes back."
Despite heavy security around Farrukhabad, the clash raised questions over actions taken by Uttar Pradesh police and government.
Senior police official earlier was quoted as saying, "We have arranged buses (to pack off the protesters). In case of any nuisance, we will immediately arrest the protesters and send them to jail." However, no arrest has been reported yet.
Kejriwal protested against Khurshid over alleged irregularities in his NGO Zakir Hussain Memorial Trust. IAC had demanded Khurshid's resignation from Manmohan Singh's cabinet. However, Prime Minister has not made any comment on the issue so far.
