NORFOLK, Va. — Former track star Tim Montgomery has been sentenced to five years in prison on heroin charges in Virginia.

Montgomery was sentenced Friday in U.S. District Court to conspiracy to possess with intent to distribute and distribution of more than 100 grams of heroin. He entered his guilty plea in July under an agreement with the government.

He will serve the five-year term after he completes a four-year prison sentence he's serving for a check-kiting conspiracy in New York.

A contrite Montgomery apologized to Judge Jerome B. Friedman at his hearing.

Montgomery won an Olympic gold medal in the 400-meter relay at the 2000 games and a silver in the same event four years earlier. A doping scandal wiped his achievements from the books.
