The Delhi poll body on Thursday, 9 May, issued a notice to BJP's South Delhi candidate Ramesh Bidhuri for allegedly using a Hindi slur against Delhi Chief Minister Arvind Kejriwal at a public meeting.
The public meeting, held on Tuesday in Mehrauli, had also seen Union Minister Giriraj Singh take part.
During the rally, Bidhuri used a Hindi slur against the Aam Aadmi Party supremo, and accused him of stalling the prosecution of former Jawaharlal Nehru University student leader Kanhaiya Kumar in a sedition case.
AAP's South Delhi candidate Raghav Chadha had lodged a complaint with the Delhi chief electoral officer in connection with the matter, following which a notice was issued to Bidhuri.
The incumbent BJP MP has to reply to the notice by 10 May.
Bidhuri is locked in a triangular fight with boxer Vijender Singh, who is making his electoral debut on a Congress ticket and AAP's debutant candidate Chadha.
Delhi will go to polls on 12 May.
