witnessed the 'ending' of this event at about 4pm today (23rd).
a male in his earlier thirties (i imagine) smashed the schmooz and job centre window with it looked like a hunk of cement (maybe taken from that nearby construction site in front of specsavaers?). cop car arrived pretty quickly, pulled him away from the scene, handcuffed him, patted him down, put in him the cop car. that's all i saw.
i didnt think i was the type of person that would stop and watch one of these situations unfold, but i walked toward it when i heard the commotion. silly me...
