SRINAGAR: Suspecting an internet breach after a video purportedly showing ailing Hurriyat leader Syed Ali Geelani was circulated on social media, J&K police on Tuesday said a "general FIR" had been filed under the Unlawful Activities (Prevention) Act to prosecute anyone in the Valley illegally using a proxy to access anything other than whitelisted sites.Inspector general (Kashmir range) Vijay Kumar said a team of cyber investigators was already onto internet users masking their identities under VPNs (virtual private networks) to "spread fabricated news to instigate people and preach separatism".The UAPA case filed at Srinagar's Cyber police station is the first since the Union Territory administration notified a list of websites that can be accessed in the Valley. The accused have also been booked under sections 188 (disobedience of order promulgated by a public servant) and 505 (incitement) of the IPC , besides 66A-b (spreading false information) of the Information Technology Act.The trigger for the FIR was a video on social media that appeared to have been posted in response to speculation about Geelani's health.Since restoring 2G internet on mobile phones on January 14, the administration has added more than 1,000 websites to the whitelist. The ban on use of social media remains.According to a police spokesperson, various agencies have reported misuse of social media by miscreants seeking to propagate secessionist ideology and incite violence. "Social media has remained their favourite tool because it can provide anonymity to the user along with a wide reach," he said.On invoking a tough law like the UAPA to crack down on internet misuse, the spokesperson said the legislation had been routinely used since the 90s to maintain public order in the Valley.
