An armed man disrupted Dutch television when he entered the building of public broadcaster NOS demanding airtime before being overpowered by police.

The man, speaking fluent Dutch and carrying what appeared to be a pistol, could be seen pacing next to a desk in an empty studio before being arrested, in footage later shown on NOS.

The NOS building in the central city of Hilversum was evacuated. The incident interrupted NOS's 8.00pm newscast on Thursday, with a message on screen telling viewers no broadcast was "available at this time".

When the channel came back on air it broadcast a video of the incident.

Wearing a dark suit, white shirt and dark tie, the gunman could be seen speaking calmly to a voice off-camera as he claimed to represent a "hackers collective", in a short video aired on NOS.

He can be heard telling the voice that he "wanted to talk about things that are of world importance".

"We were hired by intelligence services. We have heard things that call society into question," he said.

"Once my message has been sent, we'll shake hands and you'll be able to go home."
He immediately dropped his weapon and raised his arms when five armed officers stormed in to restrain him, yelling at him to drop his gun.

"I dropped it, I dropped it," he replied off-screen.

A police voice was then heard saying: "The situation is under control."

Speaking live on NOS, general director Jan de Jong said police were combing the building and that nobody had been injured.
