UPDATE: Man suspected of throwing semen on women arrested outside SW Portland Safeway

Police are asking for help identifying a man suspected of throwing semen on women in Portland-area stores.

The man follows women, throws semen on them and walks away, Portland police said in a news release. A police spokesman said the man is suspected of such activity at Lamb's Garden Home Marketplace, Safeway stores in Milwaukie and Southwest Portland, and a Kmart in Beaverton.

Detectives think he may have thrown semen at other people who didn't realize it, police said.

The Kmart incident happened in January 2016, a Beaverton police spokesman said in an email.

He said a woman was shopping with two children when a man started following her. She felt a wet substance hit her and turned to see the man holding a cup, the spokesman said. The man left after she confronted him.

Portland police said the man — who's in his 20s to 40s and has a short-to-medium build and height — was in a white, four-door sedan on April 5 at a Safeway store on Southwest Barbur Boulevard.

They ask anyone who sees the him while he's committing a crime to call 911. Anyone who knows the identity of the man or any other alleged victims should contact Detective Chris Traynor at 503-823-0889 or christopher.traynor@portlandoregon.gov.
