Here are a few:
1: Riot police and baltaguia attack protesters on Alfi Bey St.
2: Police and baltaguia gang up to beat a protester.
3: Police officer points out protesters to attack for baltaguia and orders them to attack.
(Baltaguia is a colloquial word for hired thug. They are used by police to beat up people.)
Hopefully more comment later, as I am swamped, but a picture is worth a thousand words.
