In February 1984 Durrani formed a company, Merex Corp, which traded in parts for military and commercial aircraft, and by his own account reached sales of $16m in 1986.[1][2] He was arrested in October 1986 and subsequently convicted of trading Hawk missile parts to Iran, in what Durrani maintained were actions authorised by leading US government figures (specifically, Oliver North) as part of the Iran-Contra affair with the specific aim of his shipment leading to the freeing of US hostages held in Lebanon.[1][3][4] In denying Durrani bail, the judge described him as "enjoy[ing] an exorbitant lifestyle replete with material luxuries and one which causes him to travel the globe to meet with his business associates."[2] Durrani was sentenced to 10 years (and a $2m fine), and released after five years, in September 1992.[1][5] Durrani said that many of his deals were financed via Bank of Credit and Commerce International.[6] Durrani continued to protest his innocence after his release, arguing that he was working on transactions approved by the US and Israeli governments.[7]
In 2006 Durrani was again convicted of selling arms to Iran,[12] and sentenced to more than 12 years in prison.[13] In 2007, he was in custody at the Federal Correctional Institution, Victorville.[14] Durrani was released from prison on May 5, 2016.[15]
