PHILADELPHIA (CBS) — A Philadelphia Police officer has been suspended following a domestic altercation with a female in Upper Darby.

Officials say Officer Deric Lewis was arrested following the incident on December 28, 2015.

The nature of the altercation is unclear, but officials say Lewis was off-duty at the time.
