A Metro Nashville police officer has been decommissioned after being accused of slapping a woman during an arrest.

News outlets report police say Officer Elizabeth Berry-Loucks is charged with misdemeanor assault in Tuesday's early morning incident.

Officials say Berry-Loucks was conducting a search of a woman under arrest for drug and gun charges when Berry-Loucks was stuck by an uncapped syringe hidden in the suspect's bra. Police say that's when Berry-Loucks slapped the woman in the face.

Berry-Loucks is a three-year veteran of the department. Authorities say she sought medical treatment for the needle stick and has been assigned to desk duty pending the investigation.

Police say the woman she was arresting, 22-year-old Rachel Hall, faces several charges including possession of heroin for resale. It's unclear if she has an attorney.
