A New Hampshire woman on Monday sued Bill Cosby for defamation, saying he falsely accused her of lying last year when she publicly charged he raped her in 1965.

The suit follows similar legal actions in federal court in Massachusetts, where Cosby lives, and California, contending that the 78-year-old actor, best known for his role in the 1980s "The Cosby Show," wrongly claimed that women he had sexually assaulted had lied about him.

More than 50 women have come forward to accuse Cosby of sexually assaulting them after plying them with drugs or alcohol, allegations Cosby has denied.

The comedian has never been criminally charged and many of the alleged incidents date back decades so the statute of limitations for prosecution has long run out.
