Recently, our partners at GOOD shared the story of a would-be kidnapper who chased a woman into a karate dojo and got what was coming to him.

A week later, we have another story of poetic justice from Brazil.

Polyana Viana is a 26-year-old mixed martial artist with an impressive 10-2 record. On Saturday January 5, she stood outside of an apartment building waiting for an Uber when a sketchy guy approached her.

He asked her the time and she told him, but he wouldn’t leave. “Give me the phone,” the thief said motioning to her smart phone. “Don’t try to react, because I’m armed.”

The thief half-concealed a gun with one hand, but Viana thought the visable part of the object was “too soft” to be a weapon. So she opened up a can of whoop ass on the thief that he had no idea was coming.

“I threw two punches and a kick,” Viana told MMA Junkie. “He fell, then I caught him in a rear-naked choke. Then I sat him down in the same place we were before and said, ‘Now we’ll wait for the police.’”

The thief then dropped the “gun” which was actually made of cardboard.

UFC president Dana White shared a photo of the thief’s rearranged face after the altercation.

The thief asked to be released from her MMA hold, but Viana wouldn’t let go until the police arrived. According to Viana, the thief was happy when the police arrived “because he was scared I was going to beat him up more.”
