Barrett, who landed in Pakistan from Turkey on August 5, was earlier transported to Lahore from Islamabad airport last night by the Federal Investigation Agency on Pakistan International Airlines flight PK-657.
The US national later travelled to New York on PIA flight PK-711 from Lahore’s Allama Iqbal International Airport amid tight security.
In a joint raid by FIA and police officials at a guesthouse in the capital, Barrett was arrested on August 6 after he returned to Pakistan despite being deported to the US in 2011.
The 33-year-old Alabama native had spent four years in Pakistan, where he married a local woman and had two children, before being sent out of the country after being detained near a sensitive military installation.
Barrett had claimed that he come back to Pakistan to explore the possibility of permanently moving here, adding that he was cleared of all the charges levelled against him by Pakistan’s apex court.
He had been insisting that his 2016 visit to Pakistan was legal.
The interior ministry decided to deport him on August 12 although cleared Barrett of espionage charges. Later a Rawalpindi court on Thursday also ordered to deport the US national from Pakistan.
Khan told media in one of his briefings that Barrett was never suspected of spying, but he was involved in ‘wrongdoing’.
He had said Barrett was detained at a guesthouse in Islamabad after he submitted incorrect information in a visa application to the Pakistani Consulate in Houston.
Barrett managed to obtain a Pakistani visa from Pakistan’s consulate in Houston, Texas, in June. Even The immigration counter at Benazir Bhutto International Airport allowed him to enter the country.
Taking notice of the negligence on part of the immigration department, the interior minister had ordered a probe into how he managed to re-enter Pakistan.
