Two separate unpleasant near-misses happened to Campaign members recently on cycle routes on the edges of Cambridge. In one of them, a fence wire was stretched across a cycle path with the intention of knocking cyclists off their bikes. In the other, someone scattered about forty rocks on a dark path, not necessarily with any intent to cause injury.
Watch out for repeats of these events so that they never get worse than near misses. If you find anything as nasty as the fence wire, first take it down so that no-one else is injured, and then call the police as soon as possible. If you cannot make it safe, call 999; otherwise consider the local police number: (01223) 358966 for Cambridge.
