BELGRADE, Serbia (AP) — Serbian police say they have arrested a man over a bomb scare that forced the evacuation of a Lufthansa flight to Frankfurt and caused a long delay.

Police said Thursday that the man, born in 1954, faces charges of causing panic and unrest. They say he phoned the Belgrade airport early Thursday and made the false bomb claim. His motive wasn't immediately clear.

The alert forced around 130 passengers already on the plane to disembark from the Airbus A320 which was taken off the runway for inspection by special police officers with sniffer dogs. Police later said no bomb was found and the plane eventually took off after an eight-hour delay.

Lufthansa says some of the passengers have been rebooked on other flights.
