An Iranian-American engineer accused of attempting to ship stolen documentation on a high-tech military plane to Iran has been indicted, US authorities say.
A grand jury in the US state of Connecticut charged Mozaffar Khazaee, 59, with two counts of transporting stolen goods.
He was arrested on 9 January for trying to smuggle thousands of pages of F-35 Joint Strike Fighter documents.
If convicted, he faces up to 20 years in prison.
Mr Khazaee is accused of transporting, transmitting and transferring in interstate commerce goods obtained by theft, conversion or fraud, according to court documents.
