A suspected Pakistani spy, who was arrested in the national capital, worked as a technician in a mobile phone repair shop in north-east Delhi for the past three years, police sources said on Monday.
Jabbar alias Syed Amir Ali, who was caught by Immigration officials at Delhi airport last Saturday, lived in Shahdara area.
"He was working in a mobile repair shop on Loni Road in Mansarovar Park for the past three years as a technician," the official said, adding that his employer had claimed that Jabbar was introduced to him by a neighbour.
Investigators have questioned the shop owner as well as his landlord to ascertain how the Pakistani man managed to get a job as well as a rented accommodation.
Jabbar, believed to be hailing from Karachi, was caught while trying to board a flight to Saudi Arabia, allegedly using a fake passport he procured from Lucknow, a senior police official said.
The police have learnt that he entered India through Nepal five years ago. A police team has gone to Meerut and Lucknow to investigate how he managed to obtain a fake passport and driving license, as well as get details of his contacts there. Ali stayed in Lucknow between 2005 and 2006.
