A female kickboxer knew just what to do when a sex attacker targeted her.

According to The Telegraph, the woman, who has been taking kickboxing lesson for two years, as well as a self-defense class, knocked Mark Willis out when police said he attacked her last year.

The victim told the jury that Willis climbed on top of her, telling her to "Be quiet and do as I tell you and you won't get hurt," The Telegraph reported.

That's when her self-defense mode kicked in.

She told the courts that she first tried to break his arm, then got him into a scissor grip using his legs, cutting off his air supply until he passed out.  She did the moves as Willis was punching her in the face. Despite that, she was able to escape eventually and ran into her home.

Willis claims he just confronted her after she took a photo of him relieving himself in a driveway.

The jury did not believe him and convicted him of sexual assault, The Telegraph reported.

On top of the conviction of her attacker, the judge is also requesting that the woman gets a reward for taking down Willis. She said she was stunned by the recognition.
