The attached video has appeared on YouTube showing what appears to be an assault on a Sheffield tree campaigner by Sheffield Council's and Amey plc's hired 'security'. If you find this video shocking, write in complaint to: a) Your local councillor (if you live in Sheffield). b) Your local MP (for example Paul Blomfield paul.blomfield.mp@parliament.uk) if you live in Sheffield. c) South Yorkshire Police requesting they intervene. d) Anyone else you can think of.
