PORTLAND, Ore. (KOIN) — Portland detectives are requesting public assistance with identifying a group of four people that violently attacked and stabbed a man on Tuesday, Aug. 30.

Officers said they arrived at the scene and found a man bleeding profusely due to multiple stab wounds. The man was taken to a local hospital for treatment.

A blood trail left by the victim helped officers locate the scene of the crime, which allowed them to collect video surveillance that captured the violent incident. The video can be seen here (disclaimer: the video contains violent content.)
