A NAKED and drunk man was pulled out of a river by police in the US after he was too busy pleasuring himself in a park in plain sight.

Ernest Michael Kirk, 31, was sitting on a cliff bank close to the Willamette River in Clackamette Park in Oregon, where he was masturbating while in the nude during the afternoon.

But while he was pleasuring himself, he suddenly fell into the river.

Police were called at around 2pm and had to rescue the man, who was caught in the embarrassing act, the Portland Tribune reports.

They used a sheriff’s boat to go out on the water, where they located Kirk and then pulled him on to the boat and took him back to dry land.

Kirk, who was under the influence of alcohol, was disorientated when he fell and police arrived at the scene.

The Portland Tribune also reports that Kirk continued to masturbate in front of police officers who rescued him for several minutes, while they requested assistance from the Clackamas County Sheriff’s Office Marine Unit.

Police also suspect he may have been using drugs, the Oregonian reports.

He was taken to hospital and later released. Kirk was charged with public indecency and harassment, and faces consequences after a parole violation.
