Dunno, but have just returned from the Annual meeting of Members of Kings College Hospital and learned that Ruskin Park is designated as a helicopter landing pad. The poor s0ds then have to be carted out into an ambulance and bumped over pavement and road to the A&E department... Also learned that there is a 50% cut in deaths from gun and knife crime in Lambeth. NOT because people are resisting the urge to kill one another, but because when they attempt it, the A&E department are getting better at saving the victims' lives. Back to topic, it was probably some-one cycling on the pavement.
