A Phoenix police officer has been arrested on suspicion of aggravated assault after a witness told authorities the officer choked his live-in girlfriend, according to a news release issued Monday by the Phoenix Police Department.

Sutton Wohlman, 29, was booked early Monday morning at the Maricopa County Sheriff's Office jail.

Wohlman likely will face two felony charges of resisting arrest from an officer and aggravated assault.

At 11:45 p.m. Sunday, Phoenix police responded to a domestic violence call after a female witness reported intervening in the assault involving Wohlman and his girlfriend at their home. Wohlman's girlfriend suffered minor injuries.

The first officer who arrived tried to detain Wohlman by placing him in handcuffs, but Wohlman resisted, according to Phoenix police.

One of the officers arresting Wohlman suffered minor injuries in the scuffle, said Sgt. Trent Crump, a spokesman for Phoenix police.

Wohlman was taken into custody after being treated at a local hospital for an injury to his forehead during the struggle with officers, according to Phoenix police.

Wohlman and his girlfriend had been living together for four months, Crump said. Authorities believe the couple came home from a night of drinking before the assault took place, and Wohlman is believed to have been under the influence during the assault.

He is being placed on paid administrative leave while investigations continue.

Wohlman is an officer for the Squaw Peak Precinct and has been with the Phoenix Police Department for three years.

"We employ people, and these kinds of things occur," Crump said.
