The U.S. Marshals Oregon Fugitive Task Force announced that Kevin Anthony Briggs was arrested in Portland on Friday night.
Briggs is a felon and required to register as a sex offender after a conviction for raping and kidnapping his former girlfriend in Helena, Mont., in 2003. He was 17 and she was 14. After the rape conviction, Briggs was assigned to intensive supervision in Billings.
In August 2004, his grandmother reported Briggs left her house in the middle of the night and hadn't returned. He was arrested in October 2005 in Humboldt County.
The 28-year-old Briggs was wanted for escaping from the Bozeman Police Department on Feb. 1 after being arrested on suspicion of aggravated assault, attempted sexual intercourse without consent and assault on a peace officer. The FBI added a federal charge of unlawful flight to avoid prosecution.
Authorities say he was spotted about 6: 45 p.m. Friday in a van and arrested without incident.
