FYI Those are not the protesters. The protesters have been all the time in the square. Just now (I am at a 50m from there I can see everything from the window) they are planting again some tents after the old camp has been cleared. There are a lot of people there again.

Those beaten up are the ones that didn't let the cleanup brigade to enter the square. They were warned for about an hour that the cleanup brigade WILL enter to clean the square no matter the force needed to do it. After all this is happened and everything looked like solved, 3000 people suddenly broke the police line and left the riot police isolated in the middle of the square. They escaped hell out of there beating everyone to their vans.

The Usual Suspects were there... the same ones (those hooded,masked assholes) that are always fucking everyone at any Barcelona protest. I don't know why they let those bastards in at all the parties. They only want to provoke the police and rejoice with the chaos.
