Nachiketa Vaghrekar, who claimed to be BJP general secretary of Ahmednagar unit in Maharashtra and that he reveres Anna Hazare, accused Kejriwal of "betraying Hazare and betraying people".
Shouting 'Anna Hazare Zindabad', he entered the press conference venue and threw a can of black ink on Kejriwal. Some ink also splashed on his colleagues Manish Sisodia, Sanjay Singh, lawyers Prashant Bhushan and Shanti Bhushan who were also present at the media conference.
Kejriwal was addressing the media to refute allegations labelled against him that AAP's campaign for Delhi assembly elections was being run unfairly with unaccounted-for money.
