REDMOND, OR -- Just two weeks after a text message sent Redmond’s Ridgeview High School into a brief lockdown, Redmond High initiated what the district is calling “safety protocols” over threat concerns.

School officials say students were asked to stay in their classrooms Thursday morning. Police determined within minutes that it was a false report and students resumed normal activity.

The district would not comment on the nature of the rumor that prompted the response, although one source called it a "misunderstanding."
