US authorities have arrested a military engineer on suspicion of giving secrets involving nuclear weapons, fighter jets and missiles to Israel in the 1980s.
Ben-Ami Kadish was detained for participating in a conspiracy to disclose documents related to national defence, the justice department said.
Mr Kadish worked at the army's Armament Research, Development and Engineering Centre in New Jersey from 1979 to 1985.
He is accused of giving material to an Israeli consular official whilst there.
His handler has been named by justice officials as the former consul for Science Affairs at the Israeli Consulate General in Manhattan, reportedly the same person who dealt with Jonathan Jay Pollard, who is serving life in prison for spying for Israel.
Pollard passed thousands of documents to Israeli agents whilst working at the US defence department. He was convicted in 1985.
