So an hour and a half ago, an armed man walked into the Dutch national tv station saying that he wanted to say something live on air. He didn't actually get the chance and police was quickly at the scene.
In general this doesn't appear to be an act of terrorism. There were no deaths nor injuries; when police fell in he dropped his gun and surrendered in a few seconds. He didn't wanted to make any victims.
Afterwards from the information that was released, the suspect claimed he came from a hackers collective and made himself appear more like a whistle blower and not anything close to a terrorist.
You can watch a video here. You probably won't get what he says, but at the end you can see the police capturing him.
