PORTLAND, Ore (KOIN) — Officials say there is no active threat after three Portland-area schools were put on lockdown or lockout late Tuesday morning.

Around 11:20 a.m, Roosevelt High School was been placed on lockdown while Astor Elementary School and George Middle School were placed on lockout. Portland Public Schools reportedly learned of a student allegedly robbing another student with a weapon.

PPS says the lockdown and lockouts were in place until the armed student could be located.

Staff completed a sweep of the campus and police have finished up at Roosevelt High, as of 1 p.m. Officials say there is no active threat and the situation is secure.

Thankfully, no injuries were reported.

Roosevelt High sent a statement to families saying they are releasing students for the remainder of the day.

“Students who take PPS transportation will remain at school until we connect with families,” the statement read. “We will be doing controlled release, releasing students by sections of the building.  Students are asked to get their belongings and depart campus immediately. Students will have access to lunch as they leave campus.”

Another update is expected to be sent to families later in the day.

Police investigate threat to Seaside High School

Seaside School District said the police warned a possible threat of violence against the school was received by a Seaside High School student on social media.

Authorities said the possible threat was found by a screenshot of a conversation on Instagram, posted by an unknown person.

During the investigation, police learned that the Instagram account was created an hour before posting the messages and the account was then deleted.

School resource officer Justin Gagnon and the FBI found the threat was not credible.

Class was canceled Tuesday out of an abundance of caution — and to allow more time for the investigation.
