After conducting a lie-detector test on Punjab superintendent of police (SP) Salvinder Singh, the National Investigation Agency (NIA) will now subject three others, including his jeweller friend who was kidnapped with him by suspected terrorists before the Pathankot air force station attack, to polygraphy test.
The caretaker of a shrine, the officer claimed to have visited before the incident, will also be subjected to the test.
NIA sources said after Salvinder’s name was cleared, scientific tests on his jeweller friend Rajesh Verma, cook Madan Gopal and caretaker of ‘Panj Peer Dargah’ Somraj would be conducted this week.
Singh, who was questioned about the sequence of events ahead of the terror strike for a fortnight and subjected to various tests, may be called again if something new emerges from the polygraph examination of the three.
While Verma was left on the road with his throat slit on the intervening night of December 31 and January 1, Gopal and Salvinder, currently posted as assistant commandant of 75th battalion of Punjab Armed Police (PAP), Jalandhar, were released some distance away before the alleged terrorists left to attack the air base.
The NIA probing the audacious attack said the terrorists, at least some of them, had taken shelter in a shed inside the air base on the morning of January 1. The anti-terror agency is probing whether somebody at the strategically important facility had facilitated their entry there.
The focus of investigation has now shifted to whether the terrorists were provided help internally at the base as they apparently knew which of the sheds belonging to the Military Engineering Services (MES) was vacant, they said.
The terrorists could also manoeuvre from one side of the base to another with ease, suggesting they either knew the topography of the IAF base or were guided. The terrorists also received calls on Rajesh Verma’s phone that was recovered from the encounter site, sources said.
