Shocking Moment Female Fighter Punches Fan Who 'Performed S*x Act' During Photo Shoot

A man reportedly caught performing a s-x act while watching a swimwear photoshoot was given a huge surprise when he realised the woman he was fawning over was actually an MMA fighter.

A quick punch to the face left the man in no doubt as to who he was dealing with.

The startling incident occurred as MMA fighter Joyce Vieira and a friend were taking photos on the Praia do Braga beach in the town of Cabo Frio in the Brazilian state of Rio de Janeiro.

Vieira says the alleged pervert performed a s-x act in front of her, before Vieira and her friend decided to take action.

She said: “When I looked over there he had his shorts down and was standing on a path where people pass all the time, including children.”

In the photos, the martial artist, dressed in a black swimsuit, can be seen punching the man who is topless but dressed in swimming shorts.

Vieira registered the case with police and a man was later arrested for committing an 'obscene act' but has since been released after giving a statement and denying the crime.

After his release, Vieira told local media: “We feel powerless. It’s very strange because he’s going to be in the same city as me, and who knows he might be in the same places.
