A CEREMONY to toast the renewal of a couple's wedding vows after 10 years of marriage was marred by the best man launching a "ferocious" attack on another guest.

Barrister Christopher Dunn had earlier made a disgusting speech, and unzipped his trousers and exposed himself, a jury was told.

Victim David Baird-Dean from Blackburn suffered the sort of injuries associated with a high speed car crash, it was alleged.

Dunn was niggled after being given a "dressing down" over his conduct at the reception at the Harefield Hall Hotel at Pateley Bridge, North Yorkshire, which followed a packed church ceremony last summer.

Dunn, 40, of Victoria Road, Morley, Leeds, denies causing grievous bodily harm with intent on July 1st.

Dunn was asked if a tattoo, visible under his white shirt, was a white rose, said Mr Richard Haworth, prosecuting, at Preston crown court.

Dunn allegedly then said something like "I'll show you a rose", before unzipping his trousers.

"He was waving or moving it around in the belief that it was amusing and causing entertainment".

Mr Baird-Dean, the only man close by, took offence at his conduct and pulled him away.

Told his behaviour was inappropriate and unacceptable, he apologised, but later he started showing hostility or aggression, and squared up to Mr Baird-Dean who tried to usher him away.

He was then allegedly assaulted by Dunn.

A CT scan showed significant fractures to the bone structure of the face. A consultant surgeon felt that "extreme force" was used.

Such injuries could occur if the face was stamped upon or kicked while on the ground, being struck with a baseball bat or in a high velocity car crash, or even a fall from a height.

The trial continues.
