A Portland police officer was hospitalized with "serious injuries" after he was hit in the head with a pipe Saturday evening.

Officers arrived at the 4100 block of Southeast Ivon Street around 7:15 p.m. after a 9-1-1 call reported a man throwing rocks at passing cars. When one officer approached Tsegay A. Abraha near 45th Avenue and Southeast Division Street, he was struck with a pipe, Portland Police reported.

The injured officer helped detain the 36-year-old Abraha and was later admitted to a Portland hospital "for treatment of serious injuries." The police bureau has not released the officer's name.

Abraha was arrested on assault charges and taken to Multnomah County Jail. Police continue to investigate the incident along with a recent, similar pipe assault in the area.

Anyone with information should contact the Portland Police at 503-823-0479.
