LOS ANGELES (AP) — A Nigerian American has been indicted on federal stowaway charges after authorities say he breached three layers of airport security when he got on a cross-country flight with an expired boarding pass.

A federal grand jury in Los Angeles returned a two-count indictment Friday against 24-year-old Oluwaseun Noibi.

He faces up to 15 years in prison if convicted. Noibi’s public defender declined comment.
