The police detained the Jammu and Kashmir Liberation Front chairman Yasin Malik on 27 April, few hours ahead of the funeral of the party founder Amanullah Khan, who died on 26 April at a hospital in Rawalpindi, Pakistan.
"Ahead of Ghayebana Namaaz-e-Janaaza (funeral prayers in absentia) for JKLF supreme leader Amanullah Khan, Malik was arrested by police," the JKLF said in a statement.
The statement claimed that the authorities have imposed "curfew" in Maisuma, Lal Chowk, Kothibagh, Abi Guzar, Kokerbazar, Court Road, and adjoining areas in Srinagar.
The 82-year-old Kashmiri separatist leader died after a prolonged battle with chronic lung disease.
Khan was a London based Kashmiri leader, who was deported to Pakistan in 1986.
He was believed to have conspired the killing of Ravindra Mhatre, a key officer of Indian Consulate in Birmingham in 1984.
