TV prankster Johnny Knoxville has been detained for allegedly bringing a fake grenade into an airport.
Security screeners at Los Angeles International Airport detected the grenade in the Jackass stars hand luggage.
It was investigated by a bomb squad who found it did not have a firing pin or explosives.
Knoxville told police that the grenade was a prop he forgot to remove from his bag, airport spokeswoman Nancy Castles said.
The 38-year-old, whose real name is Philip John Clapp, was later released and allowed to board an American Airlines flight to Miami.
Prosecutors have yet to decide whether to charge him with bringing a prohibited item into a secure area of the airport.
Knoxville co-created and starred in the MTV series Jackass, which became known for its dangerous stunts and pranks.
He has also had acting roles in several films, including The Dukes of Hazzard and Men in Black II.
Hope he enjoys police brutality, err, I mean hospitality.
I wonder though what the odds are of him getting off with this because hes a film star.
