Here is the story:
The man complained about the bigscreen broadcasts. He did not have a 16:9 TV, but a 4:3 TV, so there was black area on the top and the bottom of the screen. He complained about this, but he was not taken seriously.
He wanted to take personel from Philips hostage as a protest, but he went into the wrong part of the building. He decided to take some hostages there instead.
But it's all over now, the guy shot himself!
