Aaron Pross, 29, of Delaware, entered the plea back in May to charges that he engaged in sexual activity while on duty and in uniform.
On Wednesday, he was sentenced Wednesday to three years of unsupervised probation. He avoided jail time.
In January, investigators found a lewd video of Pross on a 16-year-old girl’s cell phone.
Detectives also found videos and images on his phone of a handcuffed, naked woman on a police car. The woman depicted was participating in sexual activity.
Pross has since resigned from the force.
