A man carrying a knife was shot and detained by military police on Friday at Amsterdam's Schiphol Airport. "Situation safe", police said on Twitter.
The emergency prompted the authorities to evacuate part of Schiphol, one of Europe's biggest airports.
"The man threatened with a knife and the military police shot him", police spokesman Stan Verberkt told Reuters news agency.
Trains were temporarily not stopping, but are now going in and out of the airport station as normal. Although Tobias was not there at the shooting, he saw the suspect being taken away after.
The incident took place at a Starbucks cafe at the busy airport, as shocked passengers were forced to flee.
The incident did not have any effect on flight departures and arrivals, Dutch broadcaster NOS reported, citing a Schiphol representative. So far, no evidence has been revealed that the incident is terrorism-related.
Airport spokesman Roos van der Ven said Schiphol Plaza, which houses stores, bars and restaurants, was evacuated, but not the parts of the airport behind the check-in area and security checks.
They added: "Schiphol Plaza was initially evacuated but is open to the public again".
Videos on social media showed what appeared to be the suspect being taken out of the airport in a stretcher.
He since said he had been allowed back into the main terminal. "At the moment air traffic is not affected".
