Three separatist leaders were arrested here on Wednesday, a day before they were to be questioned by the NIA in Delhi. They include hardline Hurriyat leader Syed Ali Geelani's son-in-law Altaf Ahmad Shah.
The other two were identified as Ayaz Akbar and Mehrajudin Kalwal. All of them were taken to the Rajbagh police station. The Jammu and Kashmir Police said the arrests were a precaution to maintain law and order.
The National Investigation Agency has summoned the three to New Delhi for questioning on Thursday in connection with a hawala racket linked to separatist violence in Jammu and Kashmir.
