WARNING: Distressing footage. The woman is punched in the face, pulled by her hair and kicked in the stomach
A furious daughter launched a brutal knuckleduster attack on a woman she accused of sleeping with her father.
The blonde-haired daughter calls the woman a prostitute before dragging her by her hair, punching her and kicking her in the stomach.
She claims her dark-haired rival had been sleeping with her father for more than a year.
The violent footage appears to have been filmed by the attacker's daughter.
The violent daughter repeatedly shouts "this is what you do prostitutes," and attacks the woman as her daughter watches.
She also shouts: "This is for you mother."
The dark-haired woman can be heard screaming for her attacker to get off during the ordeal but her pleas are ignored.
The thug continues to use the hand with the knuckleduster, warning the woman not to touch her father again before kicking her in the stomach.
She then drags the woman by her hair and again repeats "this is what you do to prostitutes".
She finally stops her attack but continues to shout at the woman, who can be seen with blood on her forehead.
Filming comes to an end when the attacker warns: "Touch my father again and I will f***ing kill you" before screaming "prostitute".
The person filming the footage, believed to be one of the attacker's children said: "That's for you granny", before the footage ends.
The shocking video has been circulating online and has had tens of thousands of views.
One user commented: "Shame on that woman using a knuckle duster on an other woman and she kept hitting her with same hand."
While another said: "She was bad for being a home wrecker and did need a good slap but for god sake that's not on at all.
She could of had a go with her but all I can see is someone on the floor and a three times the size of her punching the head of her with a weapon."
It is unknown when the incident took place but comments on social media suggest one of the women is from the Cambridgeshire area.
