The EC had issued a notice to Kejriwal for appealing to Muslims in Delhi to votes on religious grounds and he urged it to grant him two more days to reply to the notice.
He was served a notice by EC on November 20 after he distributed pamphlets asking Muslims to vote for AAP and was asked to reply by today.
In the probe initiated against him, the Delhi CEO directed the poll officers to file a report within two days.
"Even though we have not received any complaint, but taking cognisance of media reports have asked the District Election Officers of New Delhi and North-East Delhi to go through the voter enrolment form filed by Kejriwal. They have been asked to file a report in 48 hours," said Delhi Chief Electoral Officer Vijay Dev.
The EC notice to him said, "The Commission has prima facie observed that by distributing the pamphlet (seeking Muslim votes), you have violated the provisions of the Model Code of Conduct."
The Delhi BJP had approached the Election Commission on Friday against Kejriwal alleging that he was enrolled as a voter in three different constituencies, two in Delhi and one in Uttar Pradesh.
