But a local ABC station in North Carolina say the Madoff is being treated for serious injuries consistent with an assault.
Sources told ABC11 Madoff was treated at Duke hospital in Durham last Friday and discharged earlier this week.
According to the sources, Madoff came to Duke with facial fractures, broken ribs and a collapsed lung. Prison officials would not confirm that report.
Prisons spokeswoman Traci Billingsley told the Associated Press that Madoff is being treated at the Federal Medical Center, part of the Butner Federal Correctional Complex in Butner, N.C. He was moved there Friday.
Billingsley said Thursday that Madoff was not assaulted at the prison.
Lawyer Ira Sorkin says Madoff has "had some dizzy spells and some high blood pressure."
Billingsley said Thursday that Madoff was not assaulted at the federal prison in Butner.
Duke University Medical Center earlier said Madoff had been treated there. But spokeswoman Debbe Geiger says the hospital had never had a patient by that name.
Madoff is serving a life sentence at the federal prison in Butner, N.C., after admitting to cheating investors out of billions of dollars.
