Over 90 cases pertaining to the posting of objectionable content targeting women and girls on social networking sites and sending vulgar emails were registered in 2011, besides some other important cyber crime incidents.

Cyber sleuths are in touch with the Interpol, MHA and other agencies like Computer Emergency Response Team and National Technological Research Organisation to improve monitoring and coordinating detection of cyber crimes.
