Mangum, 32, is charged with assault with a deadly weapon with intent to kill inflicting serious injury. She is being held without bond.
Investigators believe that Mangum stabbed her 46-year-old boyfriend in the torso during a dispute, police spokeswoman Kammie Michael told CBS affiliate WRAL.
The boyfriend, whose name wasn’t released by authorities, was taken to Duke University Hospital to be treated for serious injuries, while Mangum was arrested in a nearby apartment.
Police declined to comment further on the case.
Police arrested Mangum in February 2010 after an altercation between her and a different boyfriend. Police said that in that incident, she assaulted her 33-year-old boyfriend in front of her children and lit some of his clothes on fire.
She was charged with attempted murder and arson but found guilty last December of three counts of child abuse, injury to personal property and resisting a public officer. She was sentenced to 88 days in jail, which she had already served while awaiting trial.
While a student at North Carolina Central University in March 2006, Mangum worked as a stripper and performed at a party hosted by members of the Duke lacrosse team. She claimed three white players trapped her inside a bathroom and raped and sexually assaulted her.
Mike Nifong, Durham County’s district attorney at the time, had the three players indicted on rape and other charges on the basis of Mangum’s allegations, but the case later crumbled with her wavering in key details of her story.
