Areeb Majeed, suspected member of Islamic State of Iraq and Syria (ISIS), has claimed that the cadres of the terror outfit were initially suspicious about him and his three friends of being associated with security agencies and grilled them for hours before enrolling them as members, official sources said.

Majeed and his friends were recruited only after they fully convinced the cadres that all of them genuinely wanted to fight for the cause of ISIS, an officer privy to the probe said. According to NIA sources, when Majeed and his three others-- Shaheen Tanki, Fahad Shaikh and Aman Tandel--reached Mosul in Iraq in May this year, they were questioned by one Ali, a senior cadre of the ISIS.
