The patrolman allegedly attacked a National Guard soldier on Veterans Day at a local bar.
Inside Sipangos Lounge on N. Western Ave., an off-duty Oklahoma City officer sat down next to Jeremy Pospisil.
"He borrowed my lighter and we were talking about being a veteran and stuff," Pospisil said.
The police report details how Pospisil, a National Guard veteran, eventually "recognized the officer as the man his wife had an affair with."
"I wasn't upset or anything, I just wanted to clear the air so there was no animosity between us," Pospisil said. "You know, when I told him I didn't think it was a big deal."
After the wife confirmed the accusation via text message, Pospisil even bought the officer a Red Bull and vodka as a peace offering.
But the officer, enraged by the allegations, allegedly stood up, punched the victim in the face and fled the bar.
"You know what he did was uncalled for," Pospisil said. "He hit me when my back was turned and ran like a coward. There's no need for it."
"Basically the officer was in this bar and he got into a conversation which erupted into an assault when the affair was brought up," Oklahoma City Police Capt. Dexter Nelson said.
The victim suffered only minor injuries.
Oklahoma City police admit their officers are not above the law.
"We expect our officers to act accordingly in public, both on duty or off duty," Nelson said.
For his part, Pospisil doesn't think the officer should be allowed to keep his job on the police force.
"Somebody who can't make good decisions, I don't think they should be a cop," Pospisil said.
The Oklahoma City police officer accused of the assault has been put on leave while the case is investigated.
Because the officer fled the bar after the fight, he has not been arrested but he will be cited for assault and battery.
Police aren't officially releasing his name but Pospisil confirms the officer is Kris Hunter.
