New Delhi, Jul 19 (PTI): Government has cracked down on a number of websites for spreading hatred and communal tension after the Dadri incident, resulting a rise in the number of cyber crime cases registered, Lok Sabha was informed today.

Terrorist organisations like Al-Qaeeda, Hizbul Mujahdeen, ISIS and Boko Haram have been making use of the social media for recruitment, and to deal with the problem, the government will treat the issue effectively, Kiren Rijiju, Minister of State for Home Affairs, said during Question Hour.

"We have figures for the last three years. I agree and admit to the fact that there are many campaigns (on social media) to fan communal tensions and various other issues. The figure has rose in 2015, primarily because there were incident in which we could act. There was the Dadri incident, which happened. This was used to create hatred and divide. We cracked down on many portals. That is why the figure jumped," Rijiju said in response to a question.

The Dadri incident involved the lynching of man over alleged rumours of beef-eating in Uttar Pradesh last year. The meat found at his home turned out to be mutton, as per forensic lab reports.

"Government is sensitive about the whole social media that is being used. Cyber crime is a bigger threat and we are ready to face it," Rijiju said.

Admitting that the government is suffering from several challenges including lack of adequate trained manpower to deal with cyber security, the minister said it has taken several steps to deal with the problem.
