R Kelly was acquitted of all charges Friday after less than a day of jury deliberations in his child pornography trial, ending a six-year ordeal for the R&B superstar.

Kelly dabbed his face with a handkerchief and hugged each of his four attorneys after the verdict - not guilty on all 14 counts was read. The Grammy award-winning singer had faced 15 years in prison if convicted.

Minutes later, surrounded by bodyguards, he left the courthouse without comment. Dozens of fans screamed and cheered as he climbed into a waiting sport utility vehicle.

graphic sex acts

Prosecutors had argued that a video tape mailed to the Chicago Sun-Times in 2002 showed Kelly engaged in graphic sex acts with a girl as young as 13 at the time. Both Kelly, 41, and the now 23-year-old alleged victim had denied they were the ones on the tape. Neither testified during the trial.

The prosecution's star witness was a woman who said she engaged in three-way sex with Kelly and the alleged victim. Defence attorneys argued the man on the tape did not have a large mole on his back; Kelly has such a mole.

The month long trial centred on whether Kelly was the man who appears on a sexually graphic, 27-minute videotape at the heart of the case, and whether a female who also appears on it was underage.

Over seven days presenting their case, prosecutors called 22 witnesses, including several childhood friends of the alleged victim and four of her relatives who identified her as the female on the video.

fingernail-sized mole

In just two days, Kelly's lawyers called 12 witnesses. They included three relatives of the alleged victim who testified they did not recognise her as the female on the tape.

In one scene, alluded to in one count of the indictment, the man urinates on the female.

The issue of whether there was or was not a fingernail-sized mole on the man's lower back was a subject of hours of testimony. A defence witness told jurors there was no mole on his back, proving it's not Kelly, who has such a mole. But a prosecution witness displayed freeze frames of the video where a dark spot seemed to appear as the man turns to take off his pants.

One surreal moment came when a defence expert played a segment of the tape he doctored showing two headless bodies engaging in sex. The defence said that backed their argument that Kelly's likeness could have been computer-generated.

Cross examination was often heated. Several witnesses cried on the stand.

The star prosecution witness, Lisa Van Allen, became teary eyed as she told jurors she engaged in several three-way sexual encounters with Kelly and the alleged victim, including once on a basketball court. Kelly videotaped the trysts, she said.

Van Allen also claimed Kelly used to carry a duffel bag stuffed full of his home-made sex tapes.

The defence called several witnesses in a bid to discredit Van Allen, accusing her of trying to extort money from Kelly. Under cross-examination, Van Allen admitted she once stole Kelly's $20,000 diamond-studded watch from a hotel.
