Actor Nicholas Brendon has been arrested in Indiana on drug charges, Fox News has confirmed.

The "Buffy the Vampire Slayer" star, 50, was charged with prescription fraud of a controlled substance and for refusing to identify himself while stopped for an infraction on Aug. 18, according to Vigo County Jail records obtained by Fox News on Tuesday.

His attorney, Christopher Eskew, did not have a comment when reached by Fox News.

Per TMZ, Brendon was allegedly pulled over when police in Indiana found him driving erratically.

Brendon was allegedly sweating profusely and "[appearing] nervous due to a visibly racing pulse on his neck and shaking hands," according to an affidavit obtained by the outlet.

Furthermore, the affidavit maintains that when pressed for personal information by police, Brendon – whose real name is Nicholas Brendon Schultz – produced a California ID that showed his name to be "Kelton Schultz," whom he claimed was his twin brother.

Per Page Six, the actor does indeed have a twin brother, Kelly Donovan Schultz. Schultz also works in show business, according to IMDb.

Meanwhile, during the traffic stop, the manifesto from police alleges they found a "small plastic bag that contained crystal/powder residue" as well as pills and medication prescribed to "Nicholas Bender."

Soon, officers brought in a K-9 unit to inspect the vehicle as they claimed to find "signs in the vehicle that narcotics were potentially being trafficked" and allegedly discovered several more plastic bags containing traces of residue.

The gossip site said that when asked why he lied to authorities about his identity, Brendon allegedly told police that he and his brother often fill each other’s prescriptions. Additionally, the cops say that Brendon allegedly told them he had in fact ingested pills that were prescribed to his twin brother.

Brendon was then taken into custody and arrested after officers deemed he "was using his brother’s ID to procure more or that the ID … belonging to Kelton is fraudulent."
