Authorities say the woman who falsely claimed she was raped by Duke lacrosse players has been accused of stabbing her boyfriend in the chest at a North Carolina home.

Durham police say 32-year-old Crystal Mangum was arrested Sunday morning several hours after the stabbing that seriously injured her 46-year-old boyfriend.

Investigators said the two were arguing but didn't release any other details.

Mangum is charged with assault with a deadly weapon with intent to kill. She is being held without bond, and jail officials did not know If she had an attorney.

Mangum was convicted in December of several misdemeanor charges, including child abuse, in a fire that nearly destroyed her home.

As for her rape claims, the state attorney general's office later concluded there was no credible evidence an attack ever occurred.
