A robber who tried to steal a cellphone from a young woman in Rio de Janeiro learned the hard way that mugging a mixed martial arts (MMA) fighter who goes by the nickname "the Iron Lady" is not an excellent idea.
Polyana Viana, an Ultimate Fighting Championship (UFC) strawweight, brought the hapless perp down with two punches and a kick and held him in a "rear-naked choke" before making him sit and wait for the police, she told the sports website MMA Junkie.
