A would-be robber has been left bruised and bloodied after allegedly attempting to mug Brazilian UFC fighter Polyana Viana.

Viana, who is also known by her nickname The Iron Lady, told MMAJunkie a website that covers mixed martial arts she was waiting for an Uber in Rio de Janeiro on Saturday when she was approached by the man.

When he saw I saw him, he sat next to me , she said. He asked me the time, I said it, and I saw he wasnt going to leave. So I already moved to put my cell phone in my waist. And then he said, Give me the phone. Dont try to react, because Im armed. Then he put his hand over [a gun], but I realized it was too soft.

Thinking that her alleged attacker wouldnt have time to draw his weapon which was later revealed to be a piece of cardboard shaped like a gun the UFC strawweight said she stood up and threw two punches and a kick.
