Madison police and school district officials are taking extra safety precautions following what the principal of West High School described as messages "threatening violence against our school."
In an email sent to families Tuesday evening, West Principal Beth Thompson said, "We plan to continue our safety precautions tomorrow, including a full search of our building before school begins and additional security personnel and police presence at school throughout the day."
Madison police Lt. Kelly Donahue said extra officers were at the school Tuesday and will be again on Wednesday.
Donahue did not know the nature of the threat.
A threat against the school was found written on a desk Monday night. The school was open Tuesday with a heightened police presence, and students were held in class for the final period of the day.
Thompson told families a second threat against the school was found Tuesday. "We know that copycat threats can be common in situations like this; however, it is our responsibility to take any threat seriously," she wrote.
"We also ask that you talk with your child about the serious nature and consequences of making such threats, and the disruption caused by spreading rumors about them at school or on social media," Thompson said.
