According to The Sun, the 54-year-old woman attacked her husband with a kitchen knife while he slept then flushed his genitalia down the toilet.
The woman, known only as Mrs Kim, reportedly told police the man had previously been violent with her, never gave her money and spent too much time playing golf.
One of the couple's neighbour's found the man in agony after the attack after hearing him crying out. He is said to be in a 'stable' condition in hospital.
Police said they would investigate further into the wife's motive before issuing a warrant for arrest.
