Horrified locals have demanded authorities take action after a violent brawl between Brits and fellow tourists in a Vietnamese bar.
Shocking footage shows bystanders at a Da Nang restaurant screaming as a fight erupts - with one man accidently hitting his own mother in the chaos.
The video begins with a man appearing to pull a woman off her stool, trapping her in a chokehold before tackling her to the floor.
Another man then enters the frame, and the pair repeatedly beat the woman while she lies on the ground - with one of them even managing to kick his own mother by mistake.
Glass can be heard smashing as the person filming screams 'Oh my God do you want to go to jail?' and 'He just hit his own mum'.
