The Jammu and Kashmir Police are questioning a Pakistani for his alleged links with the Lashkar-e-Taiba (LeT) terrorist outfit.
Muddasir Hussain Shah, who came from Pakistan, was picked up after his name figured during the interrogation of another Pakistani, Tufail Hussain, police sources said on Wednesday.
Tufail Hussain had brought a satellite telephone with him from across the Line of Control (LoC), which divides Jammu and Kashmir between India and Pakistan.
Tufail Hussain also travelled on the bus from Rawlakote in Pakistani Kashmir to Poonch in Jammu and Kashmir three weeks ago.
Tufail Hussain was to hand over the satellite phone to Muddasir Shah, who was to deliver it to a LeT commander.
India accuses Pakistan of arming and harbouring separatists seeking to break Jammu and Kashmir from India. The separatist violence has claimed thousands of lives.
