Fraudster Madoff 'unwell'

Notorious US Ponzi schemer Bernard Madoff has been transferred to a medical facility at his North Carolina prison, according to media reports.

Prison officials would not provide any details about Madoff's medical condition, citing privacy policies.

Madoff, 71, pleaded guilty in March to defrauding his clients of billions of dollars by running the most massive Ponzi scheme in history and was sentenced to 150 years' jail.
