After a shaky start - where was the music??? - and some general ambling about aimlessly, people got it together (behind the only banner there, thanks to the anarchists for ironically being the least disorganised) and led the police on a dance round the city center streets. Eventually they penned in a most of the group but didn't section 60. After a wait, and a slow release, the demo died down. Don't know if they're regrouped since.
