A Clark County corrections deputy masturbated and ejaculated on a woman inmate earlier this month as she was locked in a changing room awaiting transportation to the Clackamas County Jail, court documents said.

The woman told investigators she did nothing to prompt Deputy Christopher North to enter a Clark County jail changing room with his penis out, wrap one arm around her back, press his body against hers and ejaculate onto her pants, tank top and chest, a probable cause affidavit said. They had been talking early July 11 about their tattoos as she was being held in the changing room for two hours because temporary holding cells were full.

She claimed their conversation changed after North lifted his jail uniform shirt to show her his tattoos and then "told her he was going to 'jerk off' when he got home from work," the affidavit said. She said North then began "staring at her funny" and said he "should have worn underwear to work because his pants were getting wet," according to the affidavit.

North, 29, is accused of indecent liberties with forcible compulsion and second-degree custodial sexual misconduct. He was booked into the Clark County Jail on Wednesday after turning himself in and then transferred to the Skamania County Jail, records show. He is being held on $50,000 bail.

North has been a Clark County Corrections deputy since January 2015 and has been on paid administrative leave since July 13, said county spokesman Sgt. Fred Neiman. He said he could release any information on the woman other than to say she was being held temporarily in Clark County on her way to another jail. North's attorney Carrie Fulton-Brown declined comment on Thursday.

The woman, fearing retaliation at the Clark County Jail, reported the incident after she was brought to the Clackamas County Jail, the affidavit said. The Oregonian does not typically identity victims of sexual abuse.

No cameras are in the Clark County jail's changing rooms or the property room outside the changing area, the affidavit said.

The woman was booked into the Clark County jail the day before the incident from Cowlitz County, remained in Clark County overnight then was sent to the changing area about 4 a.m., to change into her civilian clothes before being taken to Clackamas County, the affidavit said.

While the woman changed into yoga pants and a tank top, North opened a small door that would have allowed him to see her bare back and a breast, the affidavit said. He told her after she changed to remain in the room until a van was ready.

The woman told investigators North's masturbation comments caught her off guard. At one point, she noticed his pants zipper was down, mentioned it to him, then he pulled his penis out of his pants, the affidavit said. He put his finger to his lips indicating for her to be quiet, then spit on his hand and began masturbating, according to the affidavit.

The woman said she was in shock when he came into the changing room and ejaculated on her, the court papers said. She said she was stuck in the room, and had she been able to escape North's grasp, she would have had nowhere to go, documents said.

She identified North as the deputy who assaulted her.

Her clothes was seized as evidence. Preliminary tests done on stains found on her pants and inside of her bra found they were likely semen. Tests to determine if it was North's fluids weren't complete as of when the court affidavit was signed Thursday.

North at first denied any physical or sexual contact with the woman to investigators, claiming they only talked about tattoos and nothing unusual occurred, the affidavit said. When investigators told North they had the woman's yoga pants and tank top showing stains that appeared to be semen, the deputy claimed he took her pants out of her jail property bag at some point while she was in custody, went to his car during a lunch break and ejaculated on them twice.

North said he returned to the jail and gave the pants to another inmate to clean and dry them, the affidavit said. He then said he couldn't remember if he actually gave the pants to another inmate to clean but claimed he returned the pants to her jail property bag.

North said there was "no way" she would have known it was him who stained her pants, the affidavit said.

A county detective arranged to meet with North again Wednesday, but he consulted with Fulton-Brown, who said North wouldn't be giving any more statements to investigators, the affidavit said. Fulton-Brown said she advised him to turn himself in to police.
