Hollywood actor Ed Harris was quizzed by police at a London airport on Monday for carrying a knife in his luggage. The weapon was spotted on an X-ray scanner as the National Treasure: Book of Secrets star traveled through Heathrow airport to catch a Los Angeles-bound flight.

The star was briefly detained by officials for questioning but released without charge.

A police source tells Britain's Daily Express newspaper, "We can't reveal what the actor told us but many people carry sharp objects with them for personal hygiene reasons without understanding the security implications."
