The charges, announced by the Wayne County Prosecutor's office on Tuesday, allege that Sims and nine others stole more than 100 laptops worth $158,000 from the Detroit Public Schools and sold them on several websites and to friends. Sims is accused of receiving and concealing stolen property, a felony punishable by up to 10 years in prison.
Sims, a sophomore from Detroit who appeared in all 13 games last season and caught 11 passes for 133 yards, was indefinitely suspended Tuesday from all team activities. He was held out of the Spartans' first three games.
Athletic director Mark Hollis said in a statement that the school has been aware of Sims' legal situation since February. He said Sims will continue to have access to the school's student-athlete academic center.
"Dion informed the coaching staff of the police investigation and has kept them apprised of the progress of the investigation," Hollis said. "We will allow the legal process to play out before we make any final decision regarding his future status with the team."
The computers were stolen in December 2009 to January 2010 from five schools. Some have been tracked to Arizona, California, Florida, Minnesota, Ohio, Tennessee and Wisconsin, as well as Canada and the United Arab Emirates.
