The Tenino School District confirmed Thursday morning that they were also made aware of the potential threat Wednesday evening.

Deputies obtained a witness statement and began reviewing surveillance footage at the school.

The student who allegedly made the threats was identified through the surveillance footage with the assistance of Tenino Police Department and Tenino School District.

“Deputies developed probable cause for threats to injure school property, and the juvenile was placed under arrest prior to the start of school this morning,” Sanders said in a social media post on Thursday, May 7.
