Two employees of a Laurel County dentist have been charged with using patients' names to get drugs illegally, according to a news release from Sheriff John Root.

Root identified the two as Katrina Dixon, 35, and Ashley Coffey, 25, both of London.

Both were charged with illegally obtaining a controlled substance.

The two called in forged prescriptions to pharmacies without the knowledge of patients, then got the pills for themselves, Root said the news release.

Police arrested the two Monday but added more charges Tuesday.

Dixon is charged with illegally obtaining pain pills on 10 occasions, and Coffey is charged with getting pills eight times.

The dentist for whom Dixon and Coffey worked had no knowledge that they were involved in illegal activity, said Deputy Gilbert Acciardo Jr, spokesman for Root's office.

Police did not release the dentist's name.
