Multi-billion-dollar Ponzi scammer Bernard Madoff was hospitalized last month for a heart attack, CNBC reports. He is back in prison, the network says.
His former attorney, Ira Lee Sorkin, reached by telephone Wednesday morning, refused to comment on the report, as did a prison official.
The network said via the NBC News website that Madoff himself "confirmed the details of his health in an email to CNBC."
"I can only confirm he's at the FCI (federal correctional institute)," Bureau of Prisons spokesman Ed Ross said. "We don't give out medical information on any inmate."
Sorkin told USA TODAY that though he no longer legally represents Madoff, he is in contact with him.
Regardless, "the decision was made some time ago not to discuss his physical or mental condition," Sorkin said.
Madoff is serving a 150-year sentence at the Butner federal prison in North Carolina, near Durham, for defrauding customers in a $17 billion Ponzi scheme.
Madoff pleaded guilty in 2009 without standing trial.
