The cellphone video cuts in to show a bloodied, screaming man held on the ground by a woman applying a “triangle choke hold.”

Monique Bastos, an MMA fighter who was on her way to jiu-jitsu training, Esquire reported, said two men jumped her and stole her cellphone on a crowded street in Acailandia, Brazil. One fled, but Bastos said she managed to personally subdue the other.

"I tried to hold my phone, and I realized they were not armed. When they tried to escape, I lifted the rear wheel of the bike and they fell on the ground. The guy who took my phone ran away, but I was able to get the other one,” she told media.

Judging by the video, the second suspect received the brunt of Bastos’ anger.

The fighter said it was the second time she was forced to fight for her phone. In her last bid at vigilante justice, she squared off with two men armed with knives.

“It’s a huge risk, but I did it to defend myself and my friends, so I used what I learned,” she said.
