Keswick was the first place in Great Britain where police used riot gear. The equipment was on trial in Manchester when there was a disturbance on lake road, in which a police car was turned over. Help was summoned, and the Greater Manchester Police arrived in full riot gear, thus giving Keswick this footnote in police history.
