A man is in federal custody in Detroit after nuclear secrets and thousands of dollars were found in his luggage.
Police arrested an unemployed US citizen at the Detroit Metro Airport Wednesday.
He was on his way to Phoenix, after having made stops in Nigeria and Amsterdam.
Police say the man was stopped at customs and asked if he had any cash to declare.
He told them he only had $18,000, but security found an additional $60 in his luggage, along with information about nuclear materials and cyanide.
