A woman attacked a man in his genitals during a Christmas party, injuring him badly enough that he needed 50 stitches, authorities said.
Rebecca Arnold Dawson, 34, was charged with malicious castration in a fight early Tuesday at a party hosted by the 38-year-old man's girlfriend, police said Friday.
All three were heavily intoxicated, police Chief Frank Powers said.
Dawson is accused of grabbing the man's genitals. Police said a weapon was not used. He declined to elaborate.
"I believe he needed more than 50 stitches to repair the damage, but he is back home at this point," police Cpl. Brad Stevens said. "All we can tell you is that the injury was done with her hands."
Dawson does not have a listed phone number.
State law describes malicious castration as cutting off, maiming or disfiguring a person's genitals with the intent to hurt or render the victim impotent.
Dawson, who was released Wednesday on $50,000 (euro38,000) bond, also was charged with offenses including assault causing serious bodily injury.
The castration arrest was the first of its kind in Lillington, a town of about 3,000 roughly 50 kilometres south of Raleigh, North Carolina, Powers said.
