A Wisconsin school district has canceled all Friday classes and activities after a note threatening a shooting on campus was found Thursday, Fox-6 reported.

As reported by Fox News:

Pewaukee School District Superintendent JoAnn Sternke informed parents of the closure in a letter released by the station Thursday evening.

“This decision is being made because we are committed to the safety of all our students and staff,” Sternke wrote.

According to Sternke, a hand-written message reading “There will be a school shooting on Friday, October 2nd” was found at Pewaukee High School sometime on Thursday.

Local police were called to campus to investigate after the message was found.

The campus will be locked down at 8 p.m. local time Thursday night, and law enforcement will sweep the campus for threats sometime afterward, Sternke wrote.
