The Egyptian authorities have charged a nuclear engineer at the state's Atomic Energy Agency with spying for Israel.
Two foreigners were also charged.
At first it was believed an Irishman was one of those charged, but the Department of Foreign Affairs have confirmed that that was not the case.
Prosecutor Hesham Badawi told a news conference that Mohamed Sayed Saber Ali, 35, had taken reports from his workplace at Inshas, the site of one of Egypt's small research nuclear reactors, with the aim of handing them over to his foreign contacts for money.
They were said to have told Ali at a meeting in Hong Kong that they wanted him to work for their company from inside the Atomic Energy Agency.
