After threats on the social media platform 'Snapchat' were made, Stillwater Area High School was placed on lockdown on Tuesday.

Brenna N. Stoltz, 21, has been arrested on suspicion of terroristic theats. The school went into lockdown after a student reported that "Snapchats saying that (Stoltz) had some firearms" according to Oak Park Heights Police Chief Brian DeRosier. According to the Pioneer Press, Stoltz went to the school around noon to see a student and was not let in due to the secured entrance. The police were notified and the lockdown ended after police arrested at her grandparents' house.

DeRosier mentioned that Stoltz went to the school to see a student.

Rob Bach, the principal of Stillwater Area High School, sent out a letter to parents after the lockdown was lifted. "As a precaution, officers asked that the school be placed on modified lockdown. While there was no indication of a threat to our students or staff, we were following procedures to ensure all of our exterior doors were locked and everyone inside our building was safe.”
