PORTLAND, Ore. (KOIN) — Police surrounded the Convention Center and arrested a man Saturday after he allegedly struck another man in the head with a hammer repeatedly on a NE Portland overpass.

It happened around 5:15 p.m. near the NE Grand Avenue overpass of I-84. Police said when they got to the scene, they found a man lying in a pool of blood with multiple cuts and stab wounds. Authorities shared the above photo of a bloodied hammer.

The man was taken to the hospital and is expected to make a full recovery.

According to the Portland Police Bureau, officers got a description of the suspect and later saw him go in the Convention Center.
