WASHINGTON (AP) — U.S. authorities have detained a 12th person in connection with the Russian spy ring, but the man is not being charged with a crime, four federal law enforcement officials said Tuesday.

The officials said the man, a Russian citizen, is being detained on immigration violations and is expected to be deported from the United States later in the day.

The name of the 23-year-old man came up during the course of the FBI’s investigation into the Russian spy ring, and he entered the United States on Oct. 9 of last year, two of the officials said. All four officials spoke on condition of anonymity about the ongoing matter.

The Justice Department investigated thoroughly and would have prosecuted the man if authorities had had enough evidence to assemble a criminal case, the officials said.

The Wall Street Journal first reported on the matter on Tuesday.

To date, investigators have uncovered no evidence that the man possessed, retained or passed on sensitive or classified information, said one of the officials.

In the biggest spy swap since the Cold War, 10 Russian agents who infiltrated suburban America were deported last week in exchange for four people convicted of betraying Moscow to the West. An 11th person has been a fugitive since fleeing authorities in Cyprus following his release on bail.

The U.S. Immigration and Customs Enforcement agency had no comment on the deportation arrangements.
