The former University of Michigan football coach, who was fired and arrested earlier this week, faces three criminal charges, including home invasion and stalking in a domestic relationship, according to court documents.

The university terminated Sherrone Moore, alleging they had “credible evidence” that he engaged in an inappropriate relationship with a staff member.

Authorities said that on the same day he was dismissed, Mr Moore was detained by police in a nearby suburb in connection with an alleged assault.

The 39-year-old was formally charged on Friday afternoon, two days after his abrupt firing and arrest.

The magistrate on Friday granted Mr Moore $25,000 bail, ordered him to wear a GPS monitor and stay away from his former girlfriend, NBC News reported.

Mr Moore or his lawyer could not be reached for comment.

On Wednesday, police in Pittsfield Township, about 15 minutes from the university’s campus in Ann Arbor, said they responded at 16:10 local time (21:10 GMT) to investigate reports of an assault.

Authorities from neighbouring city Saline “assisted in locating and detaining former University of Michigan football coach Sherrone Moore”, a statement from Saline police said, according to ESPN.

Details of the alleged inappropriate relationship and assault were not released.

In a statement provided to the BBC, the school’s athletic director said that Mr Moore’s alleged inappropriate relationship “constitutes a clear violation of university policy”, and the school “maintains zero tolerance for such behavior”.

In his second year as head coach, he was due to lead the Michigan Wolverines in a storied rivalry against the University of Texas on 31 December in the Cheez-It Citrus Bowl.

He will be replaced by Biff Poggi, the team’s associate head coach.
