Mechanised On The Beat Two members of the new patrols seen at Scotland Yard today. They are (left to right) B.C. Eric Grabb of Walthamstow and P.C. Raymond Baldwin of Finchley. Their motorcycles, with silent engines, have the word "Police" across the windscreens. The vehicles being used in this new scheme are velocette L.E. and Triumph Terrier. The patrols will operate in Norwood Green, Finchley, Croydon and Walthams tow. Sixty policemen riding lightweight motorcycles are to begin a new type of patrol in four London areas, each man covering several of the beats normally patrolled by a foot policeman.
