L. Dennis Kozlowski, the imprisoned former head of Tyco International, was hospitalized with what appears to be a heart problem.
State prisons spokesman Linda Foglia said yesterday that Kozlowski, 60, is at "an outside hospital," but added that federal health law prohibited her from commenting further.
The New York Bureau of Prisons has told CNBC that Kozlowski has returned to the Midstate Correctional Facility.
A person close to Kozlowski said the former executive suffered some sort of a heart problem one day last week and had at least one stent surgically implanted. He was told that Kozlowski was expected to get out of the hospital in a couple days. The person spoke on condition of anonymity because he was not authorized to speak publicly about Kozlowski's condition.
Kozlowski was convicted in June 2005 of stealing hundreds of millions of dollars from Tyco and illegally earning hundreds of millions more by manipulating stock.
His trials made headlines with their lavish tales of excess on the company dime -- including a $2 million toga birthday party for Kozlowski's wife on a Mediterranean island and an $18 million Manhattan apartment with a $6,000 shower curtain.
The case was part of a wave of white-collar scandals that shook corporate America and outraged the country.
Kozlowski is appealing, saying he was convicted of what should have been a civil dispute between him and Tyco's board of directors.
He is serving an 8-1/3-to-25-year sentence at Mid-State Correctional Facility near Utica. It was not immediately clear where Kozlowski's hospital was located.
