The state unit of the BJP Sunday lodged a complaint with the Election Commission, alleging that Aam Aadmi Party chief Arvind Kejriwal is enrolled as a voter in three places -- two in Delhi and one in Uttar Pradesh.
The letter dated Nov 22 said Kejriwal has voter identity cards issued from Sahibabad constituency in Uttar Pradesh, and Seemapuri and New Delhi constituencies in the national capital.
The Sahibabad and Seemapuri cards bear the same identification numbers.
"We have obtained the information from the official websites of the chief electoral officers of Uttar Pradesh and Delhi," said Bharatiya Janata Party (BJP) member Satish Upadhyay.
Upadhyay and fellow party member Harish Khurana had written the letter.
"Kejriwal has violated the election laws and he is liable to be penalised if the available facts on the website are correct," he added.
"It is requested that immediate inquiry is conducted and penal action initiated against Kejriwal."
