BENSALEM, Pa. (AP) — A groom at the Parx Casino and Racing facility in suburban Philadelphia is accused of giving performance-enhancing drugs to racehorses.

The state Attorney General's Office announced Thursday that 25-year-old Marian Vega has been charged with rigging a publicly exhibited contest.

Prosecutors allege the Bensalem woman administered doses of the drug Clenbuterol to a number of horses that was beyond "accepted guidelines." Authorities say she was found with a bottle of the drug during the investigations by the state's Horse Racing Commission and Attorney General's Office.

The drug is used to treat horses with respiratory disease but has the effect of a performance-enhancing drug when it's used outside the prescribed guidelines.

It's unclear if Vega has an attorney who can comment on the charges.
