MUMBAI: Shiv Sainiks on Sunday vandalised a cyber-cafe in Kalyan, protesting against certain hate-communities on the website orkut.com, which allegedly contained derogatory material about Shivaji and the Thackeray family.

No arrests have been made so far, police sources said, though a complaint of rioting and unlawful assembly has been lodged against some forty Shiv Sena workers.

Orkut, the web networking site which allows members to form online communities, had earlier also run into trouble over a hate-community on Shivaji.

Police said only a glass-door of Meet-way cyber cafe was broken by the Sena workers, however TV visuals showed the Sainiks beating up those who were inside the cafe.

No separate cases of assault have been registered, police said.
