Carteret County sheriff's deputies responded to the Newport home of Victoria Thomas Frabutt and her 61-year-old husband, James Frabutt, around 4 a.m. James Frabutt told officers his wife cut him after tying him up, the sheriff's office said in a statement.
Deputies recovered the penis, put it on ice and handed it over to medical personnel.
James Frabutt was taken to a hospital. His condition was unknown.
The motive is unclear. Frabutt, 56, is charged with malicious castration and kidnapping of her spouse. She is being held in the Carteret County jail on $100,000 bond and is expected to appear in court Wednesday.
