The suspect has been identified as Irshad Ahmed (30), resident of Poonch district of Jammu and Kashmir, a senior police official said today.
A smart phone has also been recovered from his possession containing pictures of vital installations and sensitive equipment in the cantonment area, police said.
He has been booked under the Official Secrets Act and a case has been registered at Shahpur Kandi in Pathankot, the official said.
The arrest comes within a month of the terror attack at the Pathankot air base, which houses fighter jets and attack helicopters, in which seven security personnel were killed along with six militants.
"Irshad was entrusted with the task of collecting secret information which he then used to send to his handler Sajjad, who was passing on the information to his Pakistani handlers, who could be the ISI," the official said.
The suspect is being questioned by central and state security agencies, the official said, adding that investigation is underway.
