COPS are investigating after three mums launched into a bloody brawl at the school gates - in a row over nails.
Footage shows the shocking moment one mum repeatedly tried to bite the finger of another parent as they tussled on the primary school playground concrete.
As she refused to let go of the finger with her teeth her victim repeatedly grabbed her hair and punched her, drawing blood.
Stunned mums at the drop-off tried to pull the scrappers apart while shocked teachers pulled down classroom blinds to stop pupils witnessing the scenes.

Finger-bite victim Sophie Mckay, 32, said: “It was unbelievable. It was all over nails.

"That’s how hard she was biting me.”
She continued: “It was all in front of children as they walked into the classrooms. Everyone was screaming.
“It all started because another nail technician was worried about me moving into the trade in the same area.
“She called me a, “fat, scabby, cocky b****’ online. I weren’t having that - but I didn’t expect her to try and bite my finger off.”
The scrap took place in Darlaston, West Midlands [at Pinfold Street Primary School] on October 8.
Sophie suffered nerve damage in two fingers and had to have a tetanus shot and receive antibiotics.
Police were called and took statements but made no arrests.
The footage has not been shared on social media.
