This is the dramatic moment Disneyland visitors were seen fighting in a queue for a photo booth.

Yan Moumou, 22, and his girlfriend were taking pictures when another unsuspecting couple with their child appeared in the background at Shanghai Disney Resort.

This sparked an altercation between the young couple and Liu Moumou, 32, in Pudong on May 31.

Footage captured by tourist Xie Zonghuan shows the woman in a plaid dress and her boyfriend in a black shirt confronting the man in a white top.

They can be seen choking the father, while his wife, who was holding their daughter, tried to intervene.

However, the angry woman shoved both the mother and child aside, causing the toddler to hit her head.

Helpless, the distraught mum screamed and cried as she crouched on the ground, clutching her child, while the pair continued attacking her restrained partner.

Moments later, security guards arrived and broke up the fight, with concerned tourists stepping in to assist.

During the scuffle, the woman's dress became unbuttoned, partially exposing her chest.

Resort staff helped the injured father stand up after the brawl.

Witness Xie said the young couple had cut the line to take photos, and when they noticed the family in the background, they lashed out.

He recalled hearing the woman yell: 'What's wrong with me calling you stupid? Is it illegal for me to call you stupid? Are you upset?'

Local media reported that both men sustained scratches and bruises, while the child was not seriously hurt.
