The FBI has joined the University of Michigan police department’s investigation of former assistant football coach Matt Weiss.

Deputy chief Melissa Overton confirmed the FBI’s involvement Thursday, adding that the investigation is “extensive, ongoing and is of the utmost priority,” and covers multiple states, according to ESPN.

Weiss, who was with the team from 2021-22, was fired in January following a report of unauthorized computer access crimes at the school’s football building.

Michigan executive associate athletic director Doug Gnodtke citied that the university collected evidence that Weiss had “inappropriately accessed” accounts at Schembechler Hall, which houses the school’s football offices.

Weiss was subsequently fired following his failure to attend a staff meeting to address the “fraudulent activity involving someone accessing university emails accounts without authorization.”

Following his firing from the university, Weiss released a statement saying he is “putting this matter behind me and returning my focus to the game I love.” 

The former co-offensive coordinator and quarterbacks coach has yet to be hit with any criminal charges.

The University of Michigan’s football program is overflowing with investigations.

The team is also embroiled in a sign-stealing scandal in which staff member Connor Stalions allegedly purchased tickets to opponents’ games and led an elaborate system to scout teams’ signals.

Stalions was suspended with pay lat week when news of the NCAA investigation into the sign-stealing imbroglio broke.

The incidents come after head coach Jim Harbaugh — who could be punished for Stalions’ purported actions — served a three-game suspension for recruiting violations during the COVID-19 dead period.

The Weiss investigation is “not related to the sign-stealing allegation in any way,” Overton said, according to the Detroit Free Press.
