Police responded Friday morning to Duluth Denfeld high school after the district was sent an email containing several threatening comments.
Police determined the threats, which were targeted towards the high school, to be non-credible.
Denfeld families were notified that school would continue as normal, but as a precautionary measure, there would be an increased police presence during the school day.
School officials will not release the nature of the threats.
