THE professional conduct of five doctors who treated a fatally-wounded race marshal at the 2001 Formula One Grand Prix will be investigated by the Medical Practitioners Board of Victoria. The board yesterday confirmed it would direct formal disciplinary hearings into the conduct of the doctors associated with the treatment of volunteer track warden Graham Beveridge. Mr Beveridge, 52, from Queensland, died when he was struck by a racing car wheel at the Albert Park track, after a collision between Ralf Schumacher and Jacques Villeneuve during the 2001 race. The doctors to be investigated are Christopher David Atkin, David James Cooper, John Thomas Moloney, Paul Bernard Temme, and David Anthony Vissenga. In a coronial inquest finding, State Coroner Graeme Johnstone said he was concerned that a doctor had changed Mr Beveridge's record to show he died at the Alfred Hospital rather than at the track.
