Albert Lea High School was locked down for a time on Tuesday morning after an adult male entered the school and refused to leave.
The man entered the school around 8:30am, when the doors were open for kids arriving for class, according to Superintendent Mike Funk.
Funk says the man was initially stopped by a Hall Monitor and was taken to the Principal’s Office.
When the man refused to leave, Police were called and the man was escorted out of the building.
Police says the man, who was described as a 26 year old from the Rochester area, was taken to Mayo Clinic Health Systems in Albert Lea for a mental health evaluation.
No further information was released on the incident.
Police say no students were in danger at any point.
