Portland police say a man was found stabbed in downtown Portland on Thursday. Investigators are still trying to determine where he was wounded and by whom.

The unidentified man was found by officers around 8:05 p.m. on Southwest Broadway between Oak and Harvey Milk streets, police said. The wounded man is expected to survive.

Investigators believe the man was stabbed during an altercation involving a group of males in their teens and 20s around a half hour before 911 was called, according to police. Another person was helping the man when officers arrived.

The incident may have occurred somewhere between Southwest Ankeny Street and Burnside Street from First Avenue to Second Avenue, the Police Bureau said. No arrests or suspect information has been announced by police.

The law agency asks anyone with more information on the stabbing to call its non-emergency dispatch line at 503-823-3333.
