The graphic footage shot in Rio de Janeiro sees a shirtless man and his friend kicking the woman in the stomach so powerfully that she's flung across the ground between them. A desperate friend runs over screaming but she is hurled to the ground and hit in the face with the weapon.
The attacker - believed to be her spurned partner - takes a running kick at the woman's head as she lies on the ground, instantly knocking her out.
Shockingly, local motorcycle taxi riders stand watching with some passersby simply ignoring the savage three-minute long attack.
According to UK Mirror ,Pablo-Luiz, 41, said:
''The girl had an argument with her boyfriend. The man was accusing her of cheating and then his friend also starts to attack the girl.''Nobody tries to help because they are too scared. You step in to help, you die. you are attacked too. If not then, maybe next week or next month. Or your family are.'You see what happens to the girl friend who tries to help. She's attacked too. She's lucky it wasn't worse.
''It's a terrible thing to see. I am sad each time I see it. But you just cannot mess with these people. There is usually drugs involved as well.
''I don't know if the girl survived. Not even an ambulance came. A friend had to pay for a taxi to take her to hospital.
''People are too scared to speak out against these people in case they take revenge.' It's not known whether she survived the brutal attack
