An aggressive man without mouth and nose protection triggered a partial closure of Terminal I at Frankfurt Airport on Saturday evening - including a large-scale deployment of the federal and state police.
A patrol from the federal police spoke to the man shortly after 5 p.m. - and he said: "I'll kill you all, Allahu Akbar," said the federal police.
The emergency services had assumed a serious statement because of his aggressive behavior.
The 38-year-old then tried to flee, but was overpowered "under threat of a firearm".
The suspect known to the police was brought to the guard.
He left his luggage behind when he tried to escape.
Because of the initially unclear location, a large area of departure hall B had been cordoned off.
Defuser could give the all-clear after an investigation.
At the same time, a federal police control center reported that an armed man had allegedly been sighted in Terminal 1.
Since a connection between the two incidents could not be ruled out, the cordoning off and evacuation measures were expanded.
The regional train station at the airport was also closed.
"Slight delays in flight operations"
“The operation resulted in greater disruption to air and rail traffic at Frankfurt Airport,” the Federal Police said.
There were no flight cancellations, said a Fraport spokeswoman in the late evening.
Because of the "slight delays in flight operations", an exemption for take-offs and landings until midnight had been granted.
In the course of the evening - after about two and a half hours - the barriers were lifted again.
The 38-year-old is being investigated on suspicion of the threat and resistance to law enforcement officers, among other things.
"There are parallel investigations into the evidence of the armed people," it said.
There were more than 100 federal and state police officers as well as supporting customs officers at the airport.
