This really is justice of the sweetest kind.

While walking home from her jiu-jitsu class in Brazil, a robber tried to steal from Monique Bastos. The robber, of course, didn’t know the person he was robbing was an MMA fighter, who responded by swiftly putting the man in a headlock until police arrived.

According to MMAFighting.com’s article:

“I was going to my jiu-jitsu training when they arrived on a motorcycle and said they wanted our phones,” Bastos told MMAFighting.com. “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.”

Bastos, who has six professional MMA fights on her record and a few jiu-jitsu matches and muay thai bouts, got him into a rear-naked choke and took him to the sidewalk, where she locked a triangle choke and waited for the police.
