 Senior Congress leader P Chidambaram has criticised the centre for extending the detention of former Jammu and Kashmir chief minister Mehbooba Mufti under the stringent Public Safety Act PSA for three more months. This would make the duration of her detention longer than a year; she was detained for the first time on August 5 last year, the day the centre scrapped special status to Jammu and Kashmir and divided the state into two Union Territories.
