DETROIT -

A Michigan man faces federal charges on accusations he phoned in a bomb threat to the Superdome while the Detroit Lions were playing the New Orleans Saints in the NFL playoffs.

The U.S. Attorney's Office in New Orleans says 34-year-old Shawn H. Payton of Jackson made the call on Jan. 7, when about 70,000 people were inside the stadium in New Orleans.

The office says he made a second call 45 minutes later, saying there would be "severe consequences" if the "stupid southern team keeps winning." The Saints beat the Lions 45-28.

The FBI arrested Payton Monday. He's free on bond after appearing in Detroit federal court. He's due Feb. 14 in New Orleans federal court.
