Singer R. Kelly missed a court appearance yesterday due to the fact that his bus was stopped by police in Utah State.

R. Kelly is facing charges of child pornography, after he was accused in 2002 of filming himself having sex with a girl of 14 years old.

He pleaded not guilty, but ever since the case was opened he has to ask permission every time he leaves the state of Illinois, United Press International reports.

Because he missed a court date in Chicago on Wednesday, Judge Vincent Gaughan issued a warrant on R. Kelly’s name, but gave the R&B star time until Thursday at 9 a.m. to be in a court in Cook County, Illinois. If by that time he doesn’t appear, the warrant will go into effect.

Cook County Assistant State's Attorney Shauna Boliker said: "This is just an abuse of the process. It's disrespectful of your honor," MTV.com informs.

According to R. Kelly’s attorney, Ed Genson, the bus was stopped by police because of some snow, after a concert in Sacramento, California. Genson told Gaughan that the singer did his best in trying to make it to court on time.

Apparently the police found that the logs of Kelly’s tour bus weren’t filled correctly and that the driver looked exhausted and was forced to take a rest at a hotel, according to Daily Herald. This made the group delay by eight hours.

Kelly’s lawyers said that he was at two hours distance from the Cook County courthouse on Wednesday at 10.30.
