Four Wisconsin middle school students are facing sexual assault charges after engaging in a “sex party,” at a home over the holidays, authorities say, according to WISN.

The students, who attend Brown Deer Middle School in Brown Deer, Wisconsin, might be as young as 13-years-old and reportedly recorded the incident on their phones.

Police are recommending that the teens be charged with first and second-degree sex assault of a child, Police Chief Michael Kass from the Brown Department Police Department tells PEOPLE.

“These kids got together and one of them told a teacher in January about the sexual activities that took place,” Kass says. “They can’t consent to sex because of their age, so we think they violated the law.”

The Brown Deer school superintendent told WISN that it’s not a school matter because the alleged assaults took place off campus.

“We are deeply troubled to learn that four Brown Deer students have been arrested for sexual assault in relation to a situation that happened off school property,” Superintendent Deb Kerr said. “This situation was originally brought to the attention of the school administration by other students who were concerned for the safety of the students allegedly involved.”

Kass says that police have completed their investigation and don’t believe any adults were involved.

He also says they haven’t heard yet whether the students will be charged.
