Imprisoned fraudster Bernard Madoff who is serving a 150-year jail sentence was moved from his cell in North Carolina to a medical facility.

According to reports from the Associated Press, the 71-year-old was moved Friday. The reason for the move was not mentioned.

Madoff has been imprisoned since March after he admitted to masterminding a multibillion-dollar Ponzi scheme in which existing investors were paid returns stolen from new investors' capital.
