An armed man was arrested after entering the offices of the Dutch national broadcaster NOS, demanding to be placed on air, live and without intervention. The man, dressed in a black suit and tie, entered the studios in the city of Hilversum, after threatening a guard with a pistol, according to  witnesses.

Jan de Jong, director of NOS broadcaster, later told the microphones of the national radio: "Someone entered the building," adding that the man had, however, been arrested and removed by the #Police. De Jong said they had not yet been determined which way the man would have passed the tight #Security in the building and the editorial offices in Hilversum.

NOS later reported on its website that the man had a pistol with a silencer and he would have threatened a security guard, forcing him to take him to the editorial offices. The man's motive was clear, but there was no immediate indication that the incident was related to any act of terrorism. The incident took place around 20:00 local time, and the station cut transmission for more than an hour, in full prime time. The evening news edition was not broadcasted and instead was presented a message that stated: "Due to the circumstances, there is no transmission available at the moment."

The police quickly surrounded the building in Hilversum and staff were evacuated, according to the media on site. There were no reports of any shots fired in the building. The man allegedly had a letter saying, "I'm heavily armed. If you cooperate, nothing will happen to you." The man was directed towards an empty studio, where he was arrested about 10 minutes later and taken away by police.

NOS, in the meantime, released images of the attack, in which we see a nervous man, wandering the studio with a pistol with a silencer. After a few minutes, the police come and the man is arrested without resistance.

By the time of this publication there are not yet known details about the motivation of the attacker and what information he intended to convey, if he had been placed on the air.
