L. Dennis Kozlowski, the imprisoned former chief executive of Tyco International Ltd., has been hospitalized for an undisclosed heart problem, according to people close to the executive.
Kozlowski, 60, is serving 8 1/3 to 25 years in a New York state prison for looting Tyco and defrauding shareholders. Since May he has been incarcerated at the Mid-State Correctional Facility in Marcy, N.Y., about 250 miles from Manhattan.
“He’s at an outside hospital,” said Linda Foglia, a spokeswoman for the New York State Department of Corrections. She declined to say why Kozlowski had been hospitalized or provide details on where.
Andrew Kaufman, a lawyer for Kozlowski, declined to comment.
In June 2005 Kozlowski and his former finance chief, Mark Swartz, were convicted in state court of grand larceny, securities fraud and other crimes, for stealing $137 million in unauthorized bonuses from Tyco, abusing company loan programs and selling $410 million in inflated stock.
Swartz is serving 8 1/3 to 25 years at a prison in Rome, N.Y.
