A man traveling from Nigeria was arrested after U.S. airport officials say they found him carrying $78,883 (Ђ61,665) in cash and a laptop computer containing information about nuclear materials and cyanide.
He will be held in custody at least until Monday, a U.S. magistrate ruled Wednesday.
Assistant U.S. Attorney Leonid Feller said Sisayehiticha Dinssa, an unemployed U.S. citizen, is a potential risk to the community and federal agents want to get a warrant to search his computer more thoroughly, The Detroit News reported.
U.S. Magistrate Donald Scheer approved Feller's request to detain Dinssa. He is charged with concealing more than $10,000 (Ђ7,800) in his luggage, which carries a maximum penalty of five years in prison, plus forfeiture of the money, the Detroit Free Press reported.
Feller said Dinssa, who gave a Texas address, arrived in Detroit from Nigeria by way of Amsterdam and was headed for Phoenix, reports AP.
Dinssa was arrested at the Detroit Metropolitan Airport Tuesday. An affidavit filed in court said a dog found the scent of narcotics on cash Dinssa carried.
When agents asked him if he had any cash to declare, he said he had $18,000 (Ђ14,000), authorities said. But when agents checked his luggage, they found an additional $59,000 (Ђ46,000). When they scrolled through his laptop, they said they found the mysterious files.
