At 7.45 yesterday (Tuesday) evening the windows of Diesel on King Street had been smashed, and potential looters were waiting patiently for the police to go away and tackle disruption in Exchange Square. They didn’t look like the rioters who had congregated around Piccadilly Gardens earlier in the evening: no scarves over their faces, no small gangs, no abundance of Nike sports wear. They were unassuming looking couples, enticed by a free pair of £120 jeans.
