A man accused of impersonating a police officer and sexually assaulting a woman in North Seattle two weeks ago was charged with rape Wednesday, the King County Prosecutor's Office said.

Michael Seville Lewis, 31, faces charges of second-degree rape, first-degree extortion and first-degree criminal impersonation.

According to a probable cause affidavit, the victim was walking at about 10:30 p.m. on June 15, on Aurora Avenue North from a friend’s house to a restaurant. A man approached her and asked her “are you working?” which she understood as him asking if she was a prostitute. She said she wasn’t and refused to identify herself unless he showed her ID.

The man took a wallet out of his back pocket, opened it and showed the woman a badge, according to the documents. He also had an earpierce with a cord around his neck that led to a microphone that was tucked into his shirt.

The woman said she felt alarmed and tried to walk away, but the man kept harassing her, according to the documents. He eventually said he was part of a drug sting and the woman was lucky he wasn’t part of a prostitution sting. He told her he didn’t want to see her around again.

She walked off, but soon realized the man was following her. She decided to turn back where she came from because it was closer than the restaurant she was headed to. She called her boyfriend and said the man was following her and that she didn’t know if he was actually an undercover officer.

The woman thought she lost the man after a few blocks and turned down a side street, but she again encountered the man there, according to the documents. He repeated his claim that he was a police officer and told her that if she didn’t perform certain sex acts, she would go to jail. She told police she agreed because she felt she had to.

Police later worked with the woman to develop a sketch of the man. Officers said they received two separate tips that Lewis might be the suspect, one of which included a claim that Lewis had a history of using a badge to conduct drug rip-offs and that he was in the neighborhood when the rape took place, according to the documents.

DNA evidence recovered from the scene matched that of Lewis.

He remains in jail on $500,000 bail. He is scheduled to be arraigned July 11.
