The brother of Olympic silver medallist Fred Evans sexually assaulted a 19-year-old woman hours after celebrating his sibling’s success at the Games.
A court heard 21-year-old Jason Evans and his father’s friend, John Janes, 40, repeatedly groped the teenager on a Cardiff-bound train as they left London after the Games’ closing ceremony.
They trapped the woman between her seat and a window in a first class carriage while they forced their hands down her top and touched her breasts.
And as the terrified teenager tried to flee the train at Reading, the men surrounded her by the doors and groped her bottom and crotch, a judge heard.
It came just hours after Evans had secured his Olympic silver medal and hundreds of thousands of fans crammed on to late-night special trains after the stunning Olympic closing ceremony on August 12.
Both men had denied sexual assault charges but changed their pleas to guilty on the second day of their trial at Reading Crown Court just before the victim was to be called to give evidence.
Janes, a married father-of-six and renowned bare knuckle boxer from Cardiff, is starting an 18-month prison sentence after Judge Peter Ross blasted his “sinister behaviour”.
The judge warned Evans, also of Cardiff, that he can expect to also go to jail when he is sentenced next month.
A jury had heard how relatives and close family friends of the boxer had been at the ExCel centre in London to see him compete before enjoying the closing ceremony headlined by Coldplay.
They were all in a jubilant mood and had been drinking to celebrate the fighter’s silver medal success after he lost to Kazakhstan’s Serik Sapiyev in the Olympic final.
They boarded a 2.30am train from London Paddington to Cardiff, which had been laid on especially that night.
However, the party atmosphere soon took a dark turn when Janes and Evans set their sights on the 19-year-old passenger in first class.
Jailing Janes, Judge Ross said: “You sought out this woman. You placed your hands not just on her outer clothing but underneath her bra, touching her breasts.
“Turning to your co-defendant, you were saying words to the effect of ‘you should have a go’.
“This was a serious sexual assault. This young woman was desperate to get off the train and you and a group were waiting for her in what I can only describe as the foyer area – an air lock by the exit doors of the train.
“There, she was subjected to further humiliation where the others groped at her backside and crotch.
“She was clearly terrified at that point, not knowing what was going to happen to her.”
Janes, a self-employed gardener and married father-of-six, of New Road, Cardiff, is well-known among the traveller community as a bare knuckle fighter.
The court heard he was previously jailed for two years in 2009 for a £275,000 pounds money laundering scheme he ran with his brother.
He also served four months in 1995 for a wounding offence.
Evans, a taxi driver, of Tyla Lane, Old St Mellons, Cardiff, was told to expect jail by Judge Ross, who will sentence him on July 29 after considering probation reports.
He was bailed to return home on an electronic tag with a daily 8pm and 6am curfew to stay inside his house.
“In my view, this is so serious that a custodial sentence can be the only one applied,” the Judge warned Evans, who stood in the dock wearing a dark grey polo t-shirt.
Janes had claimed he suffered “15 minutes of madness” amid the jubilant atmosphere of Fred Evans’ medal win.
“He is bitterly ashamed by his actions,” his defence counsel, Henry Hughes, said.
“In this unique, euphoric mood, travelling home with the family of an Olympic champion, he grabbed hold of someone and it became something completely inappropriate.”
Team GB star Fred Evans, 22, has had to wrestle with personal tragedy before, when he lost his mother and four-year-old sister in a car crash in 2006.
A third defendant, Thomas Hibbs, 52, of Heol Aneurin, Caerphilly, was found not guilty of a charge of sexual assault after his co-accused changed their pleas.
