It was some fine young hebrews on mopeds. Mainly targeting take away drivers for their mopeds.
I was in the area near the attacks. Missed one by 5 mins. Pretty sure I saw them riding around and they pulled up ahead of me and were contemplating robbing me and my cousin on our way back from the gym. We were dressed much like fine hebrews and probably looked like we might give them trouble so were left alone.
I wouldn't be surprised if the take away drivers form a militia and go kick the shit out of some brews. It's been going on for a while now, but before now it was robbery at knife point
