A Portland activist accused of sexually abusing an underage boy was arrested Tuesday on suspicion of separate sexual contact with an underage girl.



Micah Rhodes, 23, is being held at the Washington County Jail on an accusation of second-degree sex abuse in connection with the girl. He was arrested after his arraignment in Multnomah County Circuit Court on charges of second- and third-degree sex abuse in connection with the boy.



Police learned of the sex abuse allegations after Rhodes was arrested on Jan. 25 on suspicion of second-degree disorderly conduct, interfering with public transportation and parole violation during a protest in downtown Portland that same day.



Rhodes, a registered sex offender, is accused of having sex with a 17-year-old boy several times in 2015 in Gresham and Troutdale, court records show. He met the boy through a dating app and the boy told investigators that Rhodes knew he was 17.

Details of the latest accusations against Rhodes were not immediately available Tuesday.

The 23-year-old was on parole in Washington County under Oregon Youth Authority supervision for sex abuse and sodomy in a separate case, court records said.

Portland police ask anyone who is a victim or has information about additional victims to contact Det. Jeff Myers at 503-823-0595 or jeff.myers@portlandoregon.gov.
