British sprinter Bernice Wilson has tested positive for anabolic steroids, UK Athletics have announced.
A sample taken from Wilson, 27 from Lincolnshire, at the Bedford International Games on June 12 was found to contain testosterone and clenbuterol.
She has been provisionally suspended from July 9 pending her response to the charge and could face a two-year ban if found guilty of doping.
Wilson represented Great Britain for the first time in March at the European Indoor Championships in Paris where she reached the semi-finals of the 60m.
She failed to qualify for last year's Commonwealth Games but this year beat the Olympic A standard of 7.30 seconds with a 7.25secs personal best.
Wilson works as a sport development officer at East Lindsey District Council.
