Days after Alam was arrested for displaying Pakistani flags in a rally in Srinagar, he has been booked under the Public safety Act (PSA).
Separatist leader Alam who is apparently more loyal to Pakistan than India, has been shifted to a jail outside the valley.
When asked about the development, senior police officer has confirmed the news.
"Yes, PSA warrants were issued against Masrat Alam yesterday (Wednesday) and the warrants were executed today (Thursday). He is being shifted for detention to a jail outside the Valley," officer told.
Sources say that Alam may face 2 years of jail under the PSA without any trail.
On April 15, youth displayed Pakistan flags and shouted Pro-Pakistan slogans in a separatist rally led Masrat Alam in Srinagar city to welcome Syed Ali Geelani.
After much outrage, the State Police arrested Alam on April 17.
Alam had been remanded into police custody by the CJM for seven days. The period of his remand would end on Saturday.
Sources in the police told IANS that Masrat Alam is being lodged in Kotbalwal jail in Jammu region.
When Alam's release had created uproar
Masrat Alam was released on March 7 by the PDP-BJP coalition government, triggering a huge controversy over the separatist's release who had been arrested during the 2010 summer unrest in the Valley.
The Mufti Muhammad Sayeed led coalition government had said that Alam's period of detention under the PSA had already expired and there had been no fresh grounds for his detention.
As many as 110 people died in violent clashes between the security forces and unruly protesters during 2010 summer unrest.
Officials believed Alam had been the mastermind behind 2010 agitation. He was arrested after announcing a reward of Rs.1 million to anybody divulging information about his whereabouts.
