Two schools in Brooklyn Park were placed on lockdown following a threat on Thursday.
Brooklyn Park Police said a male called them at 11:58 a.m. and threatened to commit acts of violence at Park Center High School, and because of that the high school and Brooklyn Middle School were placed into lockdown.
Police say students at both schools – which are in connected buildings – are safe, but the schools will remain on lockdown until further notice.
Furthermore, all schools in the City of Brooklyn Park had at least one officer on site as a precaution, although the student who made the threat didn't mention any other schools.
Police do not know who made the threats but investigators are working to determine just that.
School lockdown alerts have died down since earlier this year, when there was a spate of them across the state in the wake of the mass shooting at a school in Parkland, Florida, which left 17 dead.
The threats tend to cause schools to go into temporary lockdowns, however it's rare for a school to close for the day as a result.
