Ayaz Akbar, Altaf Shah and Mehraj ud Din Kalwal were arrested and lodged at police station Rajbagh, said a police official.

All these leaders, whose residences were raided earlier this month by the NIA, were supposed to face another round of questioning by the investigative agency in New Delhi today.

NIA has raided the residences of separatist leaders and businessmen in Kashmir to probe alleged funding by Pakistan for fuelling unrest in Jammu and Kashmir.
