Non-student entered Andover High School Monday, assaulted girl in library

ANDOVER, Minn. (FOX 9) - One boy is in custody after authorities say he went into Andover High School after the school day was over Monday and assaulted a female student as well as a teacher. 

The incident occurred around 4:30 p.m. The Anoka County Sheriff’s Office said the suspect approached the victim in the school library and punched her in the head and kicked her several times. 

A teacher intervened, pulling the suspect away from the victim and attempting to restrain him until deputies arrived. The suspect head-butted and kicked the teacher during the struggle, the sheriff’s office said. 

Deputies arrived on scene and took the suspect into custody. The suspect also mentioned a knife and threatened to kill other teachers, but deputies did not find a knife on him. 

The suspect is not an enrolled student at Andover High School, Principal Becky Brodeur said in a message to parents Monday. 

The suspect is in custody at the Lino Lakes Juvenile Detention Center and has been charged with fifth-degree assault and disorderly conduct as well as trespassing. Additional charges are pending. 

Paramedics treated the victim on scene and released her to a parent. 

Authorities do not know what provoked the assault, but early indications in the investigation suggest the suspect was engaged in a confrontation with another person outside the school prior to the assault. They believe he gained entry to the building through a secured door as another person was leaving. 

The incident remains under investigation.
