He was arrested by FBI agents as a material witness in the espionage case.

That is an internal matter.

In the intelligence community, a rumor was almost as good as a confirmation.

I know when I was here prosecuting homicides in the District of Columbia, one of the most effective units here was the cold case squad, which had on it FBI agents, as well as Metropolitan Police Department homicide detectives working together.
