A National Investigation Agency (NIA) team today visited the Sunjwan Army camp attacked by a group of Jaish-e-Mohammad (JeM) militants and examined the evidence collected by the Army from the site of the gun-battle, an official said.
Six people, including five Army personnel, were killed while 10 others were injured in the attack by JeM militants.
Three militants were also killed in retaliatory action as the operation which began yesterday continued for a second day inside the sprawling military station along the Jammu-Pathankot bypass here.
Though a case has not been registered yet, the NIA team inspected the encounter site inside the camp and examined the evidence collected by the Army, the official said, on condition of anonymity.
The NIA is mandated to probe all terror-related cases in the country as per an act of Parliament.
NIA is already investigating the November 2016 Nagrota attack case in which seven Army personnel, including two officers, and three militants were killed.
It has already submitted a chargesheet in the Pathankot air base attack case in which it had named JeM founder Masood Azhar as an accused.
The attack on the Pathankot air base took place on the intervening night of January 1-2, 2016. It claimed the lives of seven security personnel. Four militants were also killed.
Since this (Sunjwan) attack is also blamed on JeM militants, the NIA is looking for its link with previous cases which will help them in building a stronger case against Azhar and India can make a firm case at the United Nations, the official said.
