COLUMBIA, S.C. (AP) -- South Carolina authorities in the county where Michael Phelps was spotted smoking from a marijuana pipe say they are considering a criminal charge against the Olympic superstar.
Lt. Chris Cowan said Tuesday that Richland County sheriff's investigators are gathering more information about the photo, which showed the swimmer inhaling from a marijuana pipe.
Cowan did not specify what charge was being considered and declined to discuss details of the investigation.
The photograph was first shown in a British tabloid Sunday. News of the World said the picture was taken during a November house party while Phelps was visiting the University of South Carolina.
Phelps and his advisers did not dispute the photo's authenticity. He has issued a public apology.
