Ahmed Abdellatif Sherif Mohamed, the USF student indicted in the Goose Creek case, was once arrested on terrorism suspicions in his native Egypt.

Ahmed Abdellatif Sherif Mohamed, 24, an engineering graduate student and teaching assistant at the Tampa-based university, faces terrorism charges for teaching and demonstrating how to use the explosives.

According to officials familiar with the case, Mohamed has been arrested previously in Egypt on terrorism-related charges. He is said to have produced an Internet video showing how to build a remote-controlled car bomb.

Mohamed and Youssef Samir Megahed, 21, also an engineering student, were stopped for speeding Aug. 4 in Goose Creek, S.C., where they have been held on state charges. Police found pipe bombs in their car near a Navy base in South Carolina where enemy combatants have been held. They have been held in a South Carolina jail while the FBI continued to investigate whether there was a terrorism link…

Both Mohamed and Megahed are in the country legally on student visas, officials said. (emphasis added)

Question for the vigilant Michael Chertoff: How did a man with a past arrest on terrorism charges get into the US?
