A Rawalpindi court extended the physical remand of blacklisted US national Mathew Barret for three days on Tuesday.
According to details, the court also handed over Barret to Federal Investigation Agency (FIA) for further investigation.
The FIA on Saturday arrested an American citizen, who was blacklisted over espionage of nuclear installations in Pakistan, upon his entry to Islamabad.
Mathew Craig Barret, a US citizen, was blacklisted and deported from Pakistan in 2011 on his objectionable activities. The US citizen was later arrested from a guesthouse from the capital city the same day upon his entry into Islamabad.
During the proceedings, Mathew Barret stated that he had arrived in Pakistan on visa issued by Pakistani Consulate in Houston.
About his previous visit, Mathew said he had arrived in Pakistan to visit his in-laws. He denied the charges of being a spy, saying he was not involved in such activities.
“Both cases registered against me were disposed of by the Supreme Court”, he said.
