The staffer Mehmood Akhtar, who worked in the visa section of the high commission and has diplomatic immunity, was procuring critical details including about deployment of the Border Securty Force personnel along the Indo-Pak border from two other accomplices who have been arrested in New Delhi, police said.
Described as the kingpin of the spy ring, 35-year-old Akhtar belongs to the Baloch regiment of Pakistani Army and was on deputation to spy agency ISI since 2013, investigators said, adding they also probing possible involvement of more people from the Pakistani mission.
Sources in Delhi Police also did not rule out possible involvement of some BSF personnel in the racket as they believe the staffer Mehmood Akhtar and his accomplices could not have got hold of deployment details unless somebody in BSF was leaking them.
Akhtar and two others -- identified as Subhash Jangir and Maulana Ramzan-- were picked up from Delhi Zoo on Wednesday at around 10 am. Akhtar was released after around three hours of interrogation as he enjoys diplomatic immunity.
