NEW ORLEANS (AP) — An off-duty, volunteer police officer shot and wounded a man who pointed a gun at the officer and refused to drop the weapon, according to New Orleans police officials.

The 29-year-old man was taken to a hospital with a graze wound to the head on Tuesday night, New Orleans Police Superintendent Shawn Ferguson said during a news conference. The man was responsive and listed in fair condition.

The reserve officer was in full police uniform and working as a private security guard at a housing complex when he went to investigate the sound of gunshots around 9 p.m., Ferguson said.

The officer discovered an armed man near an intersection and ordered him to drop the weapon, officials said. He then shot at the man when he did not comply, Ferguson said. The officer was not injured.

The superintendent said the officer was not wearing a camera because he was off-duty.

Reserve officers are not paid to be commissioned officers but are allowed to “supplement staffing provided by commissioned full-time officers,” such as taking on private security details, according to the department’s operations manual. Such officers are given a department uniform and equipment, depending on their role.

The officer was reassigned pending the outcome of an investigation. The man has not been arrested.

Neither the officer nor the wounded man were immediately identified.
