A STAG do descended into “chaos” after a father and son from Yorkshire became embroiled in a group attack on locals.

Roy Brown, 50, and his son Nathan Brown appeared at Swansea Crown Court after admitting affray following a violent attack in Ystalyfera on March 29.

The court heard one man was punched unconscious, whilst the attack also spilled into the home of one of the victims.

Judge Geraint Walters said it was to the misfortune of the people of Ystalyfera the pair from Rotherham chose there for Nathan Brown’s stag do.

“I frankly have no idea what caused this chaos,” he said.

“You became embroiled in some sort of dispute with some of the locals.”

Harry Dickens, appearing for Nathan Brown, said the defendant “abused alcohol when he was younger” but was “not a regular drinker anymore”.

“Prior to the stag do, he was not someone who went ‘out out’,” he said.

Mr Dickens said 34-year-old Brown, who recently became a grandfather, was “deeply regretful and deeply remorseful” over his actions.

He said Brown had no memory of his actions, but accepted the prosecution’s case.

Mr Dickens described the defendant as “having taken great strides to improve himself”, but said this offence had “foregone that progress”.

Matthew Murphy, in mitigation, said Roy Brown was previously of clean character.  

“He accepts his role in how that event soured,” he said,

“He acted in the way that he did out of ill-thought and ill-judged protection for his son.”

Mr Murphy said Brown’s “usual ability to deal with circumstances left him” following a recent death in the family, although added: “This is no excuse for his behaviour”.

Addressing Nathan Brown, Judge Walters said: “You managed to strike a man so hard he fell to the floor unconscious.

“It’s time that people realise that one punch can be fatal.

“There’s far too much bravado going on.”

Judge Walters said it was only “luck” that Brown wasn’t now facing a murder charge.

Turning to Roy Brown, Judge Walters said: “How can a man of 50 who is a family man end up being party to a group attack to other youngsters within their own home, in part where one of their children was asleep upstairs?”

Nathan Brown, of Park Hill in Swallownest, was sentenced to 18 months, suspended for two years. He must complete 240 hours of unpaid work and 20 rehabilitation activity requirement days.

Roy Brown, of Pitt Street in Kimberworth, received a 14-month sentence, suspended for two years. As part of this, he must complete 180 hours of unpaid work and 18 RAR days. He received no separate penalty after admitting criminal damage.

Both defendants must pay £500 each in compensation to each of the three victims.
