Former Michigan State basketball star Mateen Cleaves -- who was the backbone of the 2000 National Championship team -- has been charged with multiple crimes in connection to an alleged sexual assault.
Officials say 39-year-old Cleaves sexually assaulted a woman he met during a charity golf event back in 2015.
Cleaves allegedly took the woman to a motel in Grand Blanc, Michigan on Sept. 15th after offering her a ride home from a nearby bar ... and held her in the room against her will and sexually assaulted her.
The 24-year-old woman says she was able to escape and got help from someone in a nearby room.
Cleaves has now been charged with unlawful imprisonment, assault with intent to commit criminal sexual penetration, criminal sexual conduct in the 2nd degree and 2 counts of criminal sexual conduct in the 3rd degree.
If convicted on all counts, Cleaves faces SERIOUS prison time.
He's expected to turn himself in Thursday morning.
The prosecutor in the case issued a strong statement against Cleaves, saying -- "The evidence in this case will show that the alleged actions of this defendant were not only criminal but arose out of the sense of entitlement sometimes found in prominent people."
