The head of the U.S. Coast Guard's internal investigations in the Northwest was arrested Sunday in Vancouver on suspicion of climbing into his co-worker's bed and sexually assaulting the colleague's girlfriend.

Jonathan Sall, 56, of Poulsbo, Washington is accused in Clark County of second-degree rape for the alleged abuse that occurred at the co-worker's home the same day Sall was arrested.

The woman told Clark County deputies that she woke up around 3 a.m. to Sall sexually assaulting her while her boyfriend was asleep next to her, according to a probable cause affidavit. She said she kicked Sall, told him to leave and saw him crawl out of the bedroom on his hands and knees.

The co-worker said he woke up and also saw Sall crawling out of the bedroom, the affidavit said. He called 911 to report the alleged abuse.

Sall was sleeping in the couple's home when deputies arrived. He claimed he had been there for a party the night before and couldn't remember what happened overnight, the affidavit said.

When asked specifically about the sexual assault, Sall said, "I have nothing more to say," according to the affidavit.

Sall was stationed in Seattle as the special agent in charge of the Northwest region for the Coast Guard Investigative Service, the agency said. He's since been removed from the position pending the outcome of the criminal case, according to the Coast Guard.
