Angry Liverpool supporters have named the man who shoved a Barcelona street seller into a fountain ahead of their Champions League clash earlier this week.
Martin Mullen has been identified as the man who was filmed shoving a local into a fountain on Tuesday in the busy Placa Reial square.
In the video a man in a navy blue fleece approaches the man and flips him head first into the water as onlookers watch and laugh.
He is understood to be a longstanding fan and a regular on away trips, according to the Liverpool Echo.
They add that the shocking footage is being investigated by police and the club.
The incident is one of two filmed at the same location where Liverpool fans pushed unsuspecting locals into the fountain in the middle of the square.
Before Wednesday's semi-final first leg chief executive officer Peter Moore took to Twitter to tell fans to treat the city better.
'We proudly sing that we've conquered all of Europe,' he wrote. 'But let's treat this beautiful city with the respect that it deserves, and act in a manner that is befitting of LFC.
'By all means have a good time, but we are Liverpool, and as such, let's visit here with grace and humility.'
It came after reports that six Liverpool fans were arrested in Catalonia.
Two workers at the Placa Reial hotel were allegedly assaulted and required medical attention, while two others suffered bruises, including a broken nose, according to reports in Mundo Deportivo.
Jurgen Klopp's men were beaten 3-0 at the Nou Camp and need to rely on a miracle now to make next month's final in Madrid.
Luis Suarez broke the deadlock midway through the first half before a late Lionel Messi brace, including a stunning free-kick, seemingly took the tie away from Liverpool.
They meet again in the return leg at Anfield next Tuesday.
