JACKSONVILLE, Fla. -- A man who allegedly returned enemas to CVS after using them has been indicted for tampering with consumer products.

Ronald Eugene Robinson, 34, could face up to 10 years in prison and a $250,000 fine if convicted, according to a release from U.S. Attorney Robert E. O'Neill.

According to the indictment, Robinson is alleged to have purchased several CVS Pharmacy Ready-to-Use Enemas between April 10 and June 15.

Robinson then used the enemas and resealed them, claiming they were unused, according to the indictment. All affected customers are believed to have been informed of the tainted purchases.

The case was investigated by the Jacksonville Sheriff's Office, the United States Food and Drug Administration and the Office of Criminal Investigations. It will be prosecuted by Assistant United States Attorney Jay Taylor.
