UFC fighter Polyana Viana beat the brakes off a would-be mugger in Brazil this past weekend, after the man approached her and demanded her cell phone. 

As seen in the instagram post shared by UFC President Dana White, that was a #badfuckingidea.

Viana, 26, told MMAJunkie she was waiting for a ride-share in Rio de Janeiro on Saturday night when the incident occurred. She described how she hit the man with "two punches and a kick" before placing the suspect in a rear-naked choke and holding him until police arrived. 

"When he saw I saw him, he sat next to me," Viana told MMAJunkie. "He asked me the time. I said it, and I saw he wasn't going to leave. So, I already moved to put my cellphone in my waist. And then he said, 'Give me the phone. Don't try to react, because I'm armed.' Then he put his hand over [a gun], but I realized it was too soft.

"He was really close to me. So, I thought, 'If it's a gun, he won't have time to draw it.' So, I stood up. I threw two punches and a kick. 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.'"

Viana (10-2 MMA, 1-1 UFC) does not have any fights scheduled so far in 2019. She last fought at UFC 227, in which she suffered a decision loss to J.J. Aldrich.
