LONDON —  A British Olympic boxer has been questioned by police on suspicion of dealing cocaine.

Bradley Saunders, a 22-year-old light welterweight, was detained Monday after a police sniffer dog found what was believed to be more than 300 grams of cocaine worth $18,200 in his back garden in northeast England.

Saunders and his girlfriend were held overnight by police and released on bail Tuesday.

Saunders was a gold medal prospect at August's Beijing Olympics, but lost his second fight.
