Amateur mixed martial arts fighter Joyce Vieira taught him a lesson.
Brazil's Vieira was taking part in a swimsuit photoshoot when she noticed a man behaving unusually while watching her.
The fighter has alleged that the man exposed himself and began masturbating, with Vieira telling Brazilian paper
Folha de São Paulo that he was
"visibly erect, making noises and groaning."
Vieira confronted the man to tell him to stop and when he continued, she made it clear that she would not hesitate to use her fighting skills to scare him off.
She claims she kicked the man but he retaliated by punching back.
"But the punch made me even angrier. I wanted to kill him," Vieira said.
According to Vieira, the man took off running after realising that he was dealing with a trained fighter before another beach-goer came to her aid.
The report claims that the man has been charged with sexual harassment although he insists that he was urinating and Vieira misunderstood the situation.
The investigation is ongoing.
