Krystel Coleman, 29, was left with a broken nose and two black eyes after Curt Hughes, 53, allegedly punched her at her sister Karyssa's wedding
The 53 year old lorry driver is said to have then hit best man, and brother-of-the-groom, Danny Smethurst, 30, and the bride's father Kevin Coleman, 52.
Ten police vehicles had to be sent to Caldecott Hall hotel in Fritton near Great Yarmouth, Norfolk, as angry wedding guests fought in the car park outside the reception.
Even the bride's mother Liza Coleman, 47, was knocked to the ground during the scuffle last Friday.
Bride Karyssa Smethurst, 28, of Gorleston, Norfolk, who is eight months pregnant, then had to drive her sister Krystel to hospital after an ambulance failed to turn up.
The groom, Ben Smethurst, 26, said the brawl started at the buffet table after his brother reached over to get a piece of chicken for his 11-year-old son.
He said: ‘Curt thought he was pushing in the queue, and called him "a fat c***". My brother just told him there was no need to use that sort of language.
A Norfolk Police spokesperson said: ‘Police were called to Caldecott Hall Hotel in Fritton, near Great Yarmouth, shortly before midnight on Friday 5 July following reports of a disturbance.
‘Officers arrived on scene to find a number of people involved in an altercation and a woman in her 20s suffered facial injuries during the incident.
‘A 53-year-old man was arrested at the scene on suspicion of assault and released on bail while the investigation continues.’
