A co-leader for “Portland’s Resistance” – a group of radical leftists who protest all things social justice – was arrested on numerous counts of sex abuse Monday for the alleged sexual assault of two teenagers.

The 23-year-old sex offender, Micah Rhodes, was already in jail for his involvement in a downtown Portland protest last week when police learned that he confided in his parole officer that he had sex with two underage teens, KOIN reports.

The parole officer told Portland police last April that Rhodes “engaged in sexual behavior with minors in 2014,” according to the report, and officers confirmed the claim after questioning Rhodes Jan. 25. The Portland’s Resistance leader told Portland Police Bureau Sex Crimes detectives “he had sex with an underage female and an underage male” but claimed he did not know they were minors at the time.

“On Monday, the Oregon State Police Sex Offender Registration Unit confirmed Rhodes is a registered sex offender. His name does not appear on the pubic state-run website because he is not considered predatory. It’s also absent because when Rhodes was convicted, his case was settled in juvenile court,” KOIN reports.

Rhodes was on parole for sex abuse and sodomy through the Oregon Youth Authority when he met the underage male victim through the gay sex hook-up app Grindr in 2015, and the two allegedly had sex several times in Gresham and Troutdale, The Oregonian reports.

Court records show the male victim “immediately” told Rhodes he was 17 years old at the time, and Rhodes responded that he was concerned about having sex with the boy because “he has (a) sex crime history and would get in trouble.”

Police also spoke with a 17-year-old female victim who alleged Rhodes knew her age when the two had sex, KOIN reports.

On Monday, a Multnomah County judge arraigned Rhodes on four felony counts of second degree sex abuse.

“All four charges relate to one juvenile victim,” Portland police Sgt. Pete Simpson told The Oregonian. “Our detectives started looking into this, after his arrest Wednesday. They found information about a prior incident, and from there, conducted their investigation.”

The charges pertain to the male victim, though Simpson told KOIN the investigation continues.

“We’re going to continue to investigate, and anybody that does have information or knowledge of other victims, we’d like them to come forward,” he said.

Rhodes is a community activist who has helped lead numerous recent protests and high school student walkouts through his affiliation with Don’t Shoot PDX and Portland’s Resistance, both of which have denied prior knowledge of his sex crimes and attempted to downplay his prominent role in the organizations.

Rhodes was arrested for disorderly conduct and interfering with a police officer during a November 21 protest. He was also among a dozen adults arrested last week during a downtown social justice protest that shut down traffic, according to The Oregonian.

He also participated in an Inauguration Day protest that featured flag burnings, as well as clashes with police and counter-protesters.

Rhodes pleaded not guilty to the alleged sex crimes and is currently jailed on a hold from the Oregon Youth Authority for the alleged parole violations.

He pleaded not guilty during a video arraignment on Monday, and he’s scheduled to return to court Feb. 7, KOIN reports.
