Mother's Day brawl breaks out at Liverpool restaurant as diners throw punches in front of shocked onlookers

This is the moment a violent brawl erupted in a crowded restaurant on Mother's Day as women threw punches and one was smacked against a mirror.

Shocking footage of the fight showed a group of women fighting in The Restaurant Bar and Grill, in Liverpool, on Sunday.

Onlookers cackled with laughter as one woman grabbed another by the hair and rained down punches on her head.

The woman being hit then turned around and pushed her attacker into a mirror, which elicited a loud bang as her skull hit the glass.

One shocked restaurant-goer shouted: 'This is our Mother's Day.'

Another onlooker added: 'She's punching her head in.'

One terrified mother could be seen protecting her daughter's head as the fight broke out in the fancy restaurant.

A man also grabbed a bottle on his table to protect it as the brawl spiralled out of control.

It is unclear what sparked the horrifying fight on what was supposed to be a day to celebrate mothers.

The restaurant was running a promotion that saw mothers receive a £20 gift voucher.

The Restaurant Bar and Grill, which serves £55 steaks and large array of wines and cocktails, refused to comment when approached by MailOnline.

Merseyside Police also refused to comment.
