The Jammu and Kashmir police has registered a case and identified several Facebook users who had posted abusive and threatening messages on the page of the only all-girls rock band of the Valley.

"A case under Section 66 A of the IT Act and Section 506 RPC (Criminal Intimidation) has been registered in police station Rajbagh with regard to the hate messages posted on the Facebook page of the Pragaash band," a police spokesman said today. He said the investigations are in full swing but refused to give any details. However, an official associated with the investigation said police have been able to identify at least six persons who had posted hate messages with the help of experts from the cyber crime cell.

"So far half a dozen Facebook users who had posted hate messages have been identified while efforts are on to identify the others," the official said on the condition of anonymity. He said the Facebook page of the band had received a large number of posts -- mostly critical -- and it would take some time to sift through all of them.
