PORTLAND, Ore. -- A man assaulted an officer while police were trying to take him into custody, officers said.

Gresham police said that during a traffic stop they discovered that Ezekiel Wayne Streeter, 21, of Portland, was wanted on an outstanding warrant for parole violation. They were trying to arrest him when he punched one officer in the face, police said.
