"Geelani has been placed under house arrest. A posse of policemen has been deployed outside the chairman's house at Hyderpora as a preventive measure to maintain law and order," a police officer said, adding that similar restriction has been slapped on Alam.
Geelani had called for a march on Friday to Tral town in South Kashmir where two youths were killed in an anti-militancy operation on Monday.
Police had on Wednesday filed a case under Unlawful Activities (Prevention) Act against Geelani and separatist leader Masarat Alam Bhat for allegedly raising anti-national slogans during a rally in Srinagar.
Earlier in the day, Masarat denied waving Pakistani flag at the rally, but said it was a representation of the feelings, aspirations and sentiments of the people across Kashmir.
A day after being slapped with Unlawful Activities (Prevention) Act for anti-national activities, the hardline Hurriyat leader came out with clarification saying he did not wave the Pakistani flag and should not be held responsible for that.
"There was a welcome programme for Geelani. Some youth had (Pakistani) flags there. Why should I be held responsible for it?" Bhat, who was released last month after being detained under Public Safety Act for more than four years, said.
"This is a general trend in the state and not one man's doing. To hold one person responsible for it, I do not think is the right thing," he said.
