Incarcerated former football star O.J. Simpson begged for his freedom during a parole hearing in Nevada, insisting he has been "the best prisoner" since he was jailed on kidnapping and armed robbery charges.

The 66 year old was brought before a parole board on Thursday (25Jul13) after serving nearly five years behind bars for his conviction stemming from a sports memorabilia heist in Las Vegas in 2007.

During the 15-minute hearing, Simpson described how he had missed many important family events during his time in jail, telling the board, "(My years in prison) have been somewhat illuminating at times and painful a lot of times... I missed my two younger kids who worked hard getting through high school, I missed their college graduations. I missed my sister's funeral. I missed all the birthdays."

The former sports star also insisted he has been a model inmate during his incarceration, adding, "(I told prison officials) I would be the best prisoner they have ever had here, (and) I think, for the most part, I've kept my word on that."

Simpson, who is currently serving nine to 33 years on a number of charges, will find out the parole board's decision in around two weeks, but their ruling is unlikely to set him free as he is serving out concurrent sentences.

The star is also awaiting a decision on whether a judge will grant him a retrial after his lawyers argued Simpson was improperly represented during his court battle.
