Football players at a Catholic high school in Michigan were victimized with sticks in a sexual manner during alleged hazing incidents, according to a report.

It’s unclear how many players on the varsity team at De La Salle Collegiate High School in Warren were involved or how many may have been attacked by their teammates, several sources close to the matter told the Detroit Free Press.

Warren police will try to interview all 31 players in the coming days at the all-boys Catholic school to “determine exactly what happened,” Police Commissioner Bill Dwyer told The Post.

“What we’ve learned from the report today is that there was an incident that happened that could be very disturbing,” Dwyer said. “It’s premature to make any comment one way or another.”

Multiple people with knowledge of the alleged incidents said a broomstick was involved, the newspaper reports.

The school’s president, John Knight, sent an email to parents Thursday informing them that the team — which has won three state championships in five years — would forfeit a playoff game scheduled for Friday and end its season in light of the hazing allegations.

“We have recently discovered a series of hazing incidents conducted by several players on our varsity team,” the email read. “And many players on the team appear to have been aware of such hazing but failed to report it.”

The alleged hazing took place in the team’s locker room, according to the email.

“Upon an initial investigation by school administration, it appears that the hazing has deeper roots, and is more pervasive than originally thought,” the message continued.

A message seeking additional comment from school officials was not immediately returned Friday, but classes were canceled after a “serious threat” against the school was reported to Warren police.

The threat was not related to the hazing allegations and the closure was done out of an abundance of caution, Dwyer said.
