LOS ANGELES (AP) - Authorities detained Johnny Knoxville on Thursday for allegedly bringing an inert grenade into Los Angeles International Airport.
After security screeners spotted the grenade in the "Jackass" star's carry-on luggage, a bomb squad determined it lacked a firing pin or explosive. Police say Knoxville was later released and allowed to board an American Airlines flight to Miami.
Prosecutors will decide whether to charge the 38-year-old with bringing a prohibited item into a secure area of the airport, a misdemeanor. An e-mail to Knoxville's publicist was not immediately returned.
Knoxville, whose real name is Philip John Clapp, told officers the grenade was a prop he forgot to remove from his bag, Airport spokeswoman Nancy Castles said.
