The Portland Community College Rock Creek Campus was evacuated and shut down Monday due to a bomb threat.
Deputies responded to a 911 call from a payphone near campus just before 8 a.m. The caller stated there were three devices set to explode within a short period of time.
Deputies closed roads in and around campus and evacuated staff and several thousand students.
By 10:30 a.m., administrators said all daytime classes had been canceled. At 11:40 a.m., deputies said their search was completed and nothing suspicious was found.
The Washington County Sheriff's Office initially reported that the campus had reopened, but PCC administrators said the campus remained closed and would stay closed for the rest of the day and evening Monday.
Staff and students were advised they had until 8 p.m. Monday to retrieve any items they left behind during the evacuation.
PCC Rock Creek was scheduled to reopen for normal operating hours Tuesday.
All other PCC campuses and centers remained open during the Rock Creek Campus evacuation.
No arrests have been made in connection with the bomb threat, but investigators are reviewing surveillance video.
The Washington County Sheriff's Office was assisted by the Hillsboro Police Department, Beaverton Police Department, Portland Police Bureau and Port of Portland Police.
