A threatening email received by the Duluth school district this morning has led to an increased police presence at Denfeld High School.
District spokeswoman Katie Kaufman said the email contained several threatening comments toward Denfeld. The Duluth Police Department has determined the threats were not credible. However, families were notified that there would be more police present at the school as a precautionary measure. Police are working to identify the source of the email, Kaufman said.
