Former Jammu and Kashmir chief minister Mehbooba Mufti, under detention since August 5 last year, has been booked under the stringent Public Safety Act for another three months. The move comes on a day when People's Conference chief Sajad Lone was released from detention just five days short of a year since he was detained over protest against the centre's move to scrap special status to Jammu and Kashmir and divide the state into two union territories.
