Suspected ISI agent Mohammad Aijaz, who was arrested from Meerut last week, claimed the Pakistani secret service agency betrayed him and failed to keep its promises, reports said.

Aijaz, who hails from Taramadi Chowk in Pakistan's Irfanabad area, was nabbed by a team of Special Task Force personnel at Cantt railway station in Meerut on Friday.

During interrogation, Aijaz told the police that the ISI did not fulfil promises to take care of his family for the last three years, officials said.

A Special Task Force official said that though the Pakistani agency gave several promises including getting his sisters married, none of them were fulfilled.

"...they never kept their promise. The monthly payment of Rs 50,000 was also never made in full, but in instalments," The Times of India quoted STF official Ajay Pal Singh as saying.

The STF team had also recovered secret documents related to the Indian Army along with a fake voter ID and a fake Aadhaar card, said STF Inspector General Sujeet Pandey.
