A man wielding a pistol forced his way into the studios of the Dutch national broadcaster NOS this evening demanding to be allowed to go on air, but was quickly arrested.
The man, wearing a black suit and tie, entered the studio after threatening a guard with a pistol, witnesses said.
Footage aired on Dutch TV showed the man pacing in the studio with the black pistol behind his back shortly before the police stormed into the room.
"Drop it! Drop it! And get on your knees!" the police shouted, before taking him away.
An NOS radio reporter told Reuters no one had been hurt.
NOS television stopped broadcasting because the studios had been evacuated.
The man's motive was unclear; the NOS footage showed him saying: "The things that are going to be said (pause) those are very large world affairs. We were hired by the security service."
A police spokeswoman confirmed a man had entered the studios at around 1900 GMT, but could provide no details.
NOS broadcast displayed a message on its main news channel that read: "In connection with circumstances, no broadcast is available at this time."
