There were about 800 people in the camp when it was surrounded. After surrounding the camp police arrested roughly 50 people, complete with savage beatings of whoever was standing closest to them according to an eyewitness cell-phone account broadcast over web-streaming radio. The police continue to demand that the demonstrators produce documents and insist that everyone voluntarily remove themselves to a "safe place" for processing (presumably out of the range of mainstream TV cameras). The police have been arresting people in groups of 20 or so, with pauses between arrests during which they negotiate with the demonstrators. The demonstrators have reportedly refused police offers of food if they would voluntarily remove themselves.
We now have reports of heavy gassings and rapid mass arrests being made.
All of this is being filmed by numerous mainstream TV camera crews, the big question being will it all end up on the cutting-room floor. We will post updates as the situation continues to unfold.
