Senior All Party Hurriyat Conference leader and spokesperson of the Muslim League, Hakim Abdul Rashid was arrested on Thursday, official sources said.
He was held soon after he came out of Hurriyat headquarters at Rajbagh, the sources said.
Rashid used to be a member of the Democratic Freedom Party, but quit in 2001 following difference with its leader Shabir Shah. He later joined the Muslim League, a constituent of the Hurriyat.
He was arrested under the Public Safety Act on June 17, 2001, and was released on health grounds last month.
"The arrest has exposed the statement of Chief Minister Mufti Mohammed Sayeed that there would be no restrictions on political activities and no political leader would be rearrested after his release," a spokesperson of the Hurriyat said.
He expressed concern over the health of Rashid and said the arrest was uncalled for, as he was sick and had not resumed his political activities.
