ARCHIE, Mo. -- The Archie School District tweeted Wednesday morning that they canceled all classes after someone discovered a written threat inside the building.
According to a news release from the district, law enforcement is aware of the threat and they are investigating.
Superintendent Jeff Kramer said a staff member found the threat written on the bathroom stall early in the day and reported it right away.
Officials are still trying to determine who wrote the threat.
Students who rode the bus to school were dropped back off at home.
"Bus riders will be taken back home and will be dropped off as it is confirmed that an adult is present for them," the news release said.
If an adult was not home, those students were taken to a location away from the school where parents can arrange to pick them up.
Parents are advised to call (816) 898-2271 if they have questions.
The district also tweeted that junior high track will not be attending the track meet at Midway.
