Thousands of Oregon students from kindergarten to graduate school have had school disrupted due to reported threats since the mass shooting at Umpqua Community College.

Schools have gotten worrisome threats every school day since the Umpqua shooting last Thursday. None have been proven to be credible.  

Last Friday, Southwest Oregon Community College and schools in the Coquille district closed due to an apparent threat on social media. Also Friday, there were lockdowns at Forest Grove High School, and at Hogan Cedars Elementary School and Springwater Trail High School in Gresham. A 15 year-old girl was later arrested for the false alarm at Forest Grove.  

Rogue Community College was evacuated Monday due to a bomb threat.  

On Tuesday, Portland police received reports of two armed men walking near Grant High School, but officers didn’t find anyone fitting that description. The threat led to lockdowns at Grant, and at the Fernwood and Hollyrood buildings of the Beverly Cleary School.

And Wednesday, Southern Oregon University closed after a hand-written threat turned up in an academic building.  

Possible threats have also beefed up police at schools from Coos Bay to Independence.  

Police in many of the disrupted school districts say they are investigating the threats.
