A shocking video shows the moment a muscle-bound woman beats up her partner on the grass outside a block of flats.

The couple can be seen grappling in the footage before the woman grabs the man around his neck and drags him to the ground.

She then proceeds to repeatedly punch him in the head as he lies on the pavement shielding his face in desperation.

Onlookers stand by without intervening in the fight as the man tries to grab the woman’s hand.

Eventually several people step in to break up the argument and the man scrambles up off the floor.

But the woman hasn’t finished and continues to try to throw punches while others hold her back.

The video was uploaded to Facebook by VC Igwemezie on October 22 but has recently been recirculating.

It has now had more than 1.3 million views and over 29,000 shares. It is not clear where the incident took place or whether it has been reported to police
