A Nigerian citizen was arrested over the weekend by U.S. Customs and Border Protection agents as he tried to enter the U.S. at the Peace Bridge.

Emmanuel Osagie, 41, was traveling on a commercial bus late Saturday and told agents he was returning the this country after a two-week visit to Toronto, prosecutors said Tuesday. Agents found a different name on the passport he was carrying and referred him for a secondary inspection.

During that inspection, Osagie’s fingerprints were taken and his true identify was revealed, prosecutors said. He was arraigned in U.S. District Court in Buffalo Monday and remains in custody on a charge of misuse of a passport.
