The chairman of the hardline Hurriyat Conference had called a press conference at his residence on the Srinagar Airport road here.
A large posse of police personnel deployed outside Geelani's residence stopped media persons from covering the press conference.
A police officer told journalists no one would be allowed to enter the Hurriyat leader's house.
Terming the move as "frustration of the government", the amalgam said such tactics would have serious consequences.
