NEW YORK (CNN) -- Convicted swindler Bernard Madoff is being treated for "issues relating to dizziness and hypertension" at the medical facility of the prison where he is incarcerated, according to the Federal Bureau of Prisons.
Madoff was transferred to the medical wing of the Butner, North Carolina, correctional complex last Friday, said Catherine Elsea, a spokeswoman for the facility.
His attorney, Ira Lee Sorkin, declined to comment to CNN about his client's health.
A North Carolina television station originally reported that Madoff had been treated at Duke University Medical Center in Durham, North Carolina, for injuries consistent with an assault. The station has since said the injuries did not result from an assault. The medical center said Madoff has never been a patient there.
In addition, Bureau of Prisons spokeswoman Traci Billingsley told CNN that he had not been assaulted.
Madoff, 71, pleaded guilty in March to 11 counts related to running the most massive Ponzi scheme in history and was sentenced to 150 years in prison. Shortly after his sentencing in New York, he was transferred to the medium security area of the federal prison complex at Butner, where he has remained.
