An off-duty policewoman who was killed by a lorry as she helped at the scene of a crash “epitomises the very best of British policing”, a senior officer has said. <br /><br />North Yorkshire Police constable Rosie Prior, 45, was standing on the verge of the A19 at Bagby, near the town of Thirsk, on Saturday morning, after coming across a road collision, when she and two others were struck by a heavy goods vehicle (HGV). <br /><br />Pc Prior and Ryan Welford, 41, from Knaresborough, who had been involved in the first collision, died at the scene. <br /><br />A teenage boy who was a passenger in Mr Welford’s car was also struck and remains in hospital in a serious but stable condition. <br /><br />The driver of the HGV, a 65-year-old man from Berwick-upon-Tweed, was arrested on suspicion of causing death by dangerous driving. <br /><br />He has been released under investigation, North Yorkshire Police said.
