The National Investigation Agency (NIA), probing the Pathankot attack, will ask Salwinder Singh to go for a lie detector test.
According to NIA, Salwinder Singh is hiding many things from investigators. According to reports, he has three mobile phones. One mobile phone has two SIM cards. So basically he was carrying four numbers. Why a superintendent of police rank official would need four mobile numbers,” asked a senior home ministry official.
According to officials, very soon he will be formally summoned to go for polygraph test which can’t be done without his concurrence.
