Parts of Terminal 1 at Frankfurt airport have been cleared after a passenger entered the airside part of Germany's largest airport without fully completing the security check, the airport operator said on Wednesday.
"The federal police therefore cleared Piers A and A+ and passengers will undergo the security check again," Fraport told Reuters.
The spokeswoman for Fraport added the breach would lead to flight delays at the hub, German airline Lufthansa's main base.
German federal police said it was unclear whether a person who prompted an evacuation at part of Frankfurt airport by entering the airside without fully completing the security check was carrying any forbidden items.
It is also unclear whether the person accidentally continued to the airside of Germany's largest airport without completing the security check, or whether the move was intentional, a spokesman for the federal police told Reuters.
