CLOQUET, Minn. (AP/WCCO) — An Ojibwe school in northeastern Minnesota was on lockdown after a one man was shot and another arrested on the Fond du Lac Reservation Friday morning. The victim is a 45-year-old man from Minneapolis and remains in a Duluth hospital where his condition is unknown. Cloquet police say they believe his injuries are not life-threatening.

Police and tribal officials say the shooting happened around 10 a.m. at a Head Start gymnasium on the Fond du Lac Band reservation, where a funeral was taking place. Interim Cloquet Police Chief Derek Randall said the injured man was shot in the head, and was being treated at a hospital.

A 28-year-old has been taken into custody and officials say it’s unclear whether the suspect was attending the funeral or came to confront the victim.

Fond du Lac Tribal offices along with the Fond du Lac Ojibwe school were on lockdown as of noon Friday. No students were in class due to MEA, but some were present for other activities.

A woman answering the phone at the school told The Associated Press late Friday morning that everybody in the building was safe. She said the school was still in full lockdown and that no one was available to talk. She would not give her name.

Police say they believe this was an isolated incident and that there are no threats to the community.

Many Minnesota schools are closed for the Minnesota Educator Academy Conference.

The Fond du Lac Band’s reservation abuts Cloquet, near Duluth, and the band has about 4,200 members. The school includes children from preschool age through 12th grade.
