PLYMOUTH, Wis. — A 40-year-old teacher from the Plymouth School District was arrested Monday on charges of sexually assaulting a former student multiple times, sending shockwaves through the community just days before the start of the school year.
Officials said the alleged incidents occurred in Fond du Lac County. The teacher has been placed on administrative leave pending the investigation.
"Just shocked that it happened," said one student.

"I was just really surprised," said another.
"It's just a shame," added a parent
The news has left students and parents grappling with disbelief and concern about safety in their schools.
Jack Schroeder and Josh Kilian, both students in the district, expressed surprise at the allegations against someone they knew as an educator.

"She was really nice. She helped me prep for the tests and stuff — and she was really good at teaching," Jack said.
Parents Nicole Schroeder and Brenda Kilian said they've done their best in preparing each of their five children to recognize and report inappropriate behavior.

This latest case is a reminder to keep having those conversations
"I felt wow. How close of contact did this come? You never know who might be manipulating your children," Nicole said.
"I've known them for years as a teacher. They've been around a long time," Brenda noted.
"I think it's really important that kids watch out for each other because we're not going to be there. We're not going to be there all the time."
The Plymouth School District issued a statement addressing the allegations:
"Upon learning of the arrest, the district immediately placed the employee on administrative leave. We take these allegations very seriously and are now working to ensure there are no disruptions to learning in our high school courses. Efforts are underway to identify a qualified substitute in time for the first day of school."
"The reality is that it can happen anywhere," Brenda nodded.
Despite the troubling news, students said they don't want this incident to overshadow their school community.
"It's a great school. One bad thing doesn't define us," Josh said.

"It's more about the collective group of people that are here," Jack added.
The Fond du Lac District Attorney's Office has not yet received police reports in the case. The DA will review those reports before announcing formal charges.
