Former US track star Tim Montgomery [Images], an Olympic [Images] gold medallist now banned from the sport, was sentenced on Friday to five years in prison on heroin charges.

Montgomery, once known as the fastest man alive, was sentenced in Federal court in Norfolk, Virginia for conspiracy to possess with the intent to distribute more than 100 grams of heroin, according to a court document. He had pleaded guilty to the charges in July.

Montgomery won an Olympic gold medal in 2000 as a member of the US 4x100-metre relay team. Two years later, he set a 100-metre world record of 9.78 seconds but that was erased from the record books after the US anti-doping agency found he had received steroids. He was barred from competition in 2005.

Last May, Montgomery was sentenced to 46 months in prison for a check fraud and money laundering scheme in which he tried to deposit three checks worth $775,000.

That case also ensnared his former girlfriend, the sprinter Marion Jones [Images], who was sentenced to six months for misleading investigators about the check fraud scheme and lying about her steroid use.

Jones has been stripped of her five 2000 Olympic medals and banned from the sport.
