The woman was on a well-used portion of Southwest Town Center Loop East about 5:45 a.m. when a man approached, "wrapping his arms around her" and "clutching her while grabbing her buttocks with each of his hands," said Det. Jim Strovink, spokesman for the Clackamas County Sheriff’s Office.

The suspect reportedly said, "nice ass, baby."

After breaking free, the woman kicked him twice in the groin.

"The suspect keeled over slightly and stated, "nice kick," Strovink said.

Responding officers were not able to find the man. He was described as a white man in his mid to late 20s with red sideburns. He appeared to be about 5-foot-7 tall with a medium build and was wearing a black baseball cap, black sweatshirt and black sweat pants.

Authorities believe the incident was an isolated case and urged any witnesses to call the tip line at 503-723-4949.
