A woman repelled a gang of rapists — by biting the penis of one of the men, police said.

The incident unfolded on Jan. 16, when the woman was approached by two men near a small apartment in the northern French city of Amiens, the Courrier Picard reported.

The two men, and a third, then attacked her, but the 30-year-old fought back, chomping down so hard on one of their members that she drew blood, police said.

The trio of goons proceeded to beat her unconscious, according to police, who said she was taken to an area hospital in serious condition.

Two of the men have been caught, and the third remains at large, said cops.
