The beautiful UFC fighter Polyana Ivana was minding her own business in Rio De Janeiro when a wanna-be mugger tried to rob her. That was a really bad idea bro...

We live in the age of MMA people. Don't let a woman setting alone on a bench somewhere fool you. That lady very well could be a trained killer, and for this mugger he found out the hard way.

So from the details Polyana was waiting for her Uber to pull up when this wanna-be mugger sat next to her and told her not to move. And that's when she immediately got up and proceeded to beat the living sh$t outta this guy! Just look at the photo! This dude got beat up by girl, a very dangerous girl.

Now, the question is. What will he tell his cellmates once he's behind bars?
