Ten or more people associated with multibillion dollar swindler Bernard Madoff could face criminal charges in investigations in the coming months or beyond, a law enforcement source said on Tuesday.

Disgraced financier Madoff, 71, was sentenced to 150 years imprisonment on Monday after he pleaded guilty in March to orchestrating a worldwide investment scheme of as much as $65 billion.

When all is said and done, the FBI thinks there is a good chance it will be able to charge 10 or more people, said the law enforcement source, who asked not to be identified because the investigation is continuing.
