The background of this thing is hilarious too:
3 years ago, the property owner (a real-estate agency) wanted to renovate and sell their property.
But 1 old retired couple refused to move out of the building.
Then the real-estate agency - no joke - invited the punks to move into their property to scare away the remaining old couple.
The old couple didn't move out though, but became supporters of the punks and left-wingers and even went shopping for them and provided them with stuff they needed.
So, the house was occupied for the past 3 years.
Now, with immigration to Vienna booming (last year, the city grew by 30.000 people), the real-estate prices went up like crap and the agency wants to badly renovate and sell it for a nice share.
They applied for eviction and the police removed them today, a process which lasted more than 12 hours, because the occupiers blocked the entry with stuff and also the first 2 floors of the building and threw stuff out of the window. The police had to remove all the blocked stuff and make their way into the 3rd floor, where they arrested all the occupiers in the last hours ...
Don't know though what happens with the old couple now ...
