The police arrested a man at the NPO 3FM building in the Hilversum Media Park premises around 9:30 a.m. on Thursday after he held a woman hostage there for an hour and a half. The woman is unharmed and is receiving victim assistance, the police said, NU.nl reports.

The police have thus far refused comment about the suspect's identity and motives. According to the police, he threatened a woman in the parking lot in front of the building with a knife. He then forced her into the building and held her captive, authorities allege.

A police negotiator managed to make contact with the man and entered the building. A short time later a SWAT team entered and arrested the man, NOS reports.

According to police officials, the victim works for NPO, the national public broadcasting organization in the Netherlands. There were few other people in the building at the time as 3FM is broadcasting from other locations this week, according to NU.nl. No one was injured as far as is known.

A bag containing a knife was found outside the building, according to the newspaper.
