The Huntsville Police Department arrested one of its own on Thursday following an investigation into an alleged fight at a local restaurant.

Investigators allege that officer Paige Denise Pinkerton of the north precinct was off duty on Dec. 31 when she got into a physical fight with an employee at the unidentified restaurant. The employee told police Pinkerton knocked him unconscious for a short time, and the fight left him in want of medical attention.

An internal investigation was launched, leading to Pinkerton's arrest Thursday morning. The result was a third-degree assault charge. She was released on bond shortly after.

The 25-year-old uniformed officer has been with the Huntsville Police Department since February 2014. She was sworn into the 53rd session of the Huntsville Police Academy on June 20.

She is now on administrative leave pending the outcome of the case.

"We adhere to a professional tradition and a prescribed code of conduct; when that is breached we take it very seriously and we move to correct it," the police department stated in a press release.

Pinkerton is the second Huntsville police officer currently facing criminal charges. Officer Lewis Bernard Hall is facing federal bribery and conspiracy charges for allegations he helped "fix" a man's cocaine trafficking charges last summer. Lewis, who is still employed by the department, originally pleaded not guilty but just recently scheduled a change of plea hearing for Feb. 24.
