Federal officials are moving forward with deporting four men from Egypt and Jordan who were detained on immigration charges as part of an investigation into a potential terrorism threat in a Baltimore highway tunnel, a federal official said Wednesday. Mark Bastan, acting special agent in charge at the US Immigration and Customs Enforcement in Baltimore, said the four men already had broken the law by failing to show up for deportation proceedings before they were detained on Tuesday. Three of the men are from Egypt, and the other is from Jordan. The men were to be held at a detention center in Wicomico County on Maryland's Eastern Shore. Deportation procedures could take up to about a month, Bastan said.
