Police are searching for a middle-aged man who fled after his computer sparked a security alert at a German airport.
Part of Munich airport was closed for hours on Wednesday as the traveller's laptop set off an explosives detector.
Some 1,000 police scoured the airport for the man, who hastily left the security area as the alarm was raised.
Police stress that they only want to talk to the man, who may just have been in a hurry to catch a plane and failed to realise more checks were needed.
Although the man was not found, police say they have a clear image of him on camera.
German Interior Minister Thomas de Maiziere described the incident as a serious security breach and ordered a thorough investigation.
