A Manhattan man was charged with circumcising his much-younger wife after she refused to have sex, authorities said Tuesday.

Moussa Diarra, 48, wanted to have anal intercourse with the 24-year-old victim and when she said no, he forced himself on her, police said. He sodomized her before performing the horrific circumcision around 9 p.m. Sept. 14, the woman told cops.

The victim reported the assault about a week later, police said.

Diarra, who is originally from Africa, where circumcision was once common, was arrested Sept. 23, court records show. He was indicted by a grand jury six days later.

He is charged with a forcible sex act, aggravated sex abuse by compulsion, attempted assault with intent to disfigure or dismember and assault with intent to cause physical injury with a weapon, court records show.

He is being held at the Manhattan Detention Center in lieu of $20,000 cash bail or $40,000 bond. He is scheduled to appear in court Oct. 27.
