A man drove a car through the security perimeter of the Hannover airport in northern Germany on Saturday, police said, prompting authorities to suspend flights for over four hours.
The police claimed that the man was under the influence of drugs when he drove the car registered in Poland through a gate and on the apron, reported the German press agency dpa. They said that the man tried to follow a landing plan operated by the Greek airline Aegean.
The police cars stopped the vehicle and the agents overpowered the driver. Bombing experts examined the car but found no dangerous objects. No one was injured in the accident.
The federal police said that the man's motivation was not clear, but until then there were no indications that he had an extremist history or that the airport accident was connected to terrorism. They think he acted alone.
The takeoffs and landings of the aircraft resumed shortly after 8 pm.
The federal police said the driver, who is about 20 years old, was positive for amphetamines and cocaine. The police said they could not provide more information about where it came from because it did not carry an identity card.
Hanover Airport handled 5.7 million passengers last year, although it is not one of Germany's main hubs.
