At about 20:05 (CET), the airport resumed normal operations. Flights have been suspended at Hannover airport in central Germany after a man tried to drive onto the facility's apron. No other risky substances were found in the vehicle or on the driver.
Federal police were investigating whether the driver was mentally disturbed, under the influence of drugs, trying to carry out an attack or drove through the perimeter for some other reason, German news agency dpa reported.
No one was hurt in the incident, but flights were suspended for more than four hours.
The worldwide airport in Hannover handled 5.87 million passengers past year, though it isn't one of Germany's top hubs.
