A teacher at Hibbing High School has been placed on administrative leave after an investigation was launched into "various complaints."
The Hibbing Daily Tribune reports "various allegations" have been made against the teacher, who has not been named.
An external law firm is investigating the complaints, with Superintendent Johnson telling the newspaper the teacher's presence at school would have compromised the probe.
FOX 21 reports the teacher has been at the high school for "quite a while" and is tenured, with Johnson telling the TV station the investigation stems from social media posts made by adults and students.
Johnson told the Duluth News Tribune the complaints are not "specifically related to (having happened) in the classroom," but added: "It was something that we felt that we needed to do due diligence on to follow up.
"The best way to do a proper follow-up without potential issues is to place the person on leave until we can investigate."
