John Mouzon, a 16-year veteran of the Philadelphia Police Department, was arrested Monday on charges of assault and recklessly endangering another person, police said.
Mouzon, 37, was off duty when he and his girlfriend got into a fight on Harvey Street near Lincoln Drive in Germantown Monday.
Mouzon's girlfriend was briefly hospitalized at Einstein, where she was treated for bruises and scratches, police spokeswoman Officer Jillian Russell said.
Mouzon is the 32nd police officer to be arrested since 2009, and the second to be arrested this month.
On Aug. 18, Officer Sean Jang — of the 18th District in West Philadelphia — was arrested on assault charges after a fight with his ex-girlfriend.
Commissioner Charles Ramsey transferred Mouzon to administrative duties while Internal Affairs investigates the incident, police said.
Mouzon is scheduled to appear in court Nov. 9, according to court documents.
