Auston Robertson, 19, was charged Friday with third-degree criminal sexual conduct by the Ingham County Prosecutor's Office in a case unrelated to three other players being suspended from the team.
The charges stem from alleged incident April 9 in Meridian Township in MI. That player is now identified as Robertson.
"We will continue to educate and enforce high standards for the program", coach Mark Dantonio said after initially learning of the alleged incident.
This investigation is not connected to another case involving three Michigan State players and a football staff member.
The Ingham County Prosecutor's Office says Robertson has not been arraigned yet. "It is not appropriate at this time for me to comment further on this matter".
Robertson was arrested in January 2016 on a misdemeanor battery charge in connection with an October 2015 incident at Wayne.
Meridian Township police conducted the investigation.
As Freep's Chris Solari notes, this is the second major charge against Robertson who entered a diversionary program back in 2015 after another charge. Three of the warrants were for sexual crimes and the fourth was for a nonsexual crime during their investigation. All extra evidentiary materials prosecutors asked for have been turned in, and they're in the process of making a charging decision. The school has confirmed that recruiting director Curtis Blackwell is under suspension but has not confirmed he is the subject of the investigation.
