PORTLAND, Ore. (KOIN) — A person arrested Saturday for attempted murder of a police officer has escaped from Portland Police Bureau’s custody, officials said.

At 1:30 p.m. Saturday, East Precinct officers located and arrested a suspect in the attempted murder of Portland Police Officer Jennifer Pierce on December 24, 2020, near SE 39th Ave. and SE Powell Blvd. A suspect rammed their car into Pierce’s vehicle. Pierce, who discharged her firearm during the incident but did not strike the suspect, suffered a fractured pelvis from the incident.

24-year-old Portlander David Dahlen was captured after a short foot pursuit in the area of SE 101st Ave. and Insley St.

PPB Homicide Detectives were investigating due to the incident involving an officer involved shooting.

At 5:30 p.m. Saturday, detectives discovered Dahlen had escaped the secure holding cell he was in at Central Precinct in downtown Portland near SW 2nd Ave. The building was immediately locked down and additional resources were called it. It was later confirmed Dahlen had gotten out of the building and was last seen running north.

An effort to recapture Dahlen is now underway. However police say there is no reason to believe he presents a direct threat to the community.
