Police have requested website owners Google to block 'objectionable material' on its social networking site Orkut.com, following recent attacks by Shiv Sainiks on cyber cafes at Kalyan in Mumbai, protesting 'derogatory references' to the Maratha leader Shivaji and the Thackeray family.

The Computer Emergency Response Team has also been asked to take similar action on objectionable material on Orkut, Deputy Commissioner of Police, Kalyan Zone,  Anupkumar Singh told PTI on Sunday.

He said a fax stating the request has been sent and CERT's response is awaited.

Shiv Sainiks are protesting against certain 'hate-communities' on Orkut, which allegedly contained derogatory material about Shivaji and Thackeray family.

Deputy Chief Minister R R Patil, who also holds Home portfolio, had recently said action will be taken against those found guilty in the Orkut controversy and asked the Sainiks not to take law in their hands.
