IRISHMAN Shane O'Brien has been found guilty of murder after following a trial at the Old Bailey.
O'Brien stabbed 21-year-old Josh Hansen to death in a London bar in October 2015, before going on the run.
The 31-year-old was detained in Romania and brought back to London in April this year following a three-and-a-half-year international manhunt.
During that time he was added to Interpol and Europe's most wanted lists.
It took less than an hour for the jury to come to a guilty verdict, according to the BBC.
Mr Hansen was attacked in front of his girlfriend and suffered wounds to his ear and chest on October 11, 2015.
The jury heard that O'Brien 'walked calmly' out of the bar before enlisted helping from friends of his to charter a private plane to take him to the Netherlands.
In an attempt to conceal himself, O'Brien grew long hair and even covered a tattoo of his daughter's name he had on his back.
He used false identity documents to travel to Belgium, Germany and the Czech Republic.
It was in Prague he was arrested for assault, but went on the run again after being released on bail, after which he began using the alias Enzo Melloncelli.
O'Brien before the stabbing incident in 2015O'Brien told jurors he had felt threatened by Mr Hanson's "very aggressive body language" on the night of the attack. He said he felt Mr Hanson was "ready to attack".
At bar closing time he approached his victim and asked him, "what's your problem?", before pulling the knife from his jacket pocket and fatally slashing him.
He claimed he wanted to "pretend to attack" Mr Hanson in a bid to "scare him".
"From the bottom of my heart, I did not mean to touch him with that blade," O'Brien added.

Mr Hanson's mother Tracey said: "The aftermath of Josh's murder has left us broken beyond repair as Josh was taken from us in the most horrific way possible - suddenly, abruptly, viciously and violently.
"Nothing will ever erase the CCTV footage of Josh's final moments from our minds as he was struck with a knife so horrifically and callously, along with his suffering as he tried to fight for his life."
O'Brien is due to be sentenced on October 17.
