Kolkata, Mar 30 (IANS): Special police observer for West Bengal Vivek Dube, appointed by the Election Commission of India (ECI) in place of K.K. Sharma who has been shifted, will reach the state on Sunday, an official said here on Saturday.

"Vivek Dube, special police observer for the state will come to Kolkata on Sunday evening," Additional Chief Electoral Officer Sanjay Basu told the media here.

He said that Dube will look after the deployment of Central and state forces. He will also look after other matters as per the Chief Electoral Officer's instructions.
