MEDFORD, WI (WSAU) -  A north central Wisconsin school is taking extra precautions after finding evidence of a threat to safety Thursday. 

Medford students will see more police today, and they will have their backpacks and coats checked. That’s because of a threat found yesterday in a girl’s bathroom at the high school.

Neither the Taylor County Sheriff’s Department or the Medford Police would say exactly what they observed in the bathroom other than to say it is an issue affecting the safety of students and staff.

The Medford school district sent a letter home to parents saying they take these threats very seriously. Parents in the district have the option of keeping their children home today as an excused absence.
