Former University of Illinois basketball player Jereme Richmond is back in jail after authorities said he tested positive for marijuana while free on bond.

Lake County Assistant State's Attorney James Newman said Richmond was jailed Friday.

A judge raised the 19-year-old Richmond's bail to $100,000. The judge also set a 24-hour curfew that requires Richmond to stay at his family's Waukegan home once he's free unless the court gives him permission to leave to train.

Attorney Lawrence Wade asked the judge to consider Richmond's future in basketball.

Richmond has pleaded not guilty to aggravated battery and other counts stemming from an August incident involving a girlfriend.

He was once 1 of Illinois' best players. He played sparingly in one season before leaving for the NBA draft. He wasn't drafted.
