NIA summons senior Punjab police officer, friend

NEW DELHI: National Investigation Agency has summoned three persons, including senior Punjab police officer Salvinder Singh, for questioning in connection with the Pathankot terror strike as the agency awaits a Letters Rogatory from Pakistan. This is a routine investigation as some formalities have to be carried out before a charge-sheet is filed in the case. The NIA had conducted a lie-detector test on all the three and given them a clean-chit. Terrorists engaged in an 80-hour gunbattle with the security forces at the IAF base from the intervening night of January 1 and 2. Seven security personnel were killed, while four bodies of terrorists belonging to Jaish-e-Mohammed were recovered.
