An extra police presence was in place at Stillwater Area High School Friday after a threat was made to "shoot up the school" on the popular social media app Snapchat Thursday night.
"If you go to Stillwater DO NOT GO TO SCHOOL TOMORROW because there's someone threatening to shoot up the school," the message read.
The Oak Park Heights Police department investigated the threat.
They worked with the school administration to determine the possible subject. Police said the parents of the subject also cooperated.
"After a thorough investigation and cooperation with our local law enforcement, we are confident there is no existing threat to our students," the school district told parents in a recorded voicemail Friday morning.
Still, as an added precaution, extra law enforcement was stationed at the school, along with additional school district staff members.
"We have brought in extra administrators from the district level to be on hand at the school, as well as some counselors, and that's truly just to help students if they're feeling apprehensive or anxious, someone extra for them to talk to," said Carissa Keister, community engagement manager for Stillwater Area Public Schools.
Keister added that some families chose to keep students at home, although she didn't know how many.
