A US tourist who suffered permanent facial scarring during a violent assault in Dublin two years ago has praised gardaí for their efforts in tracing his attackers.

Garth Russell still has glass embedded under his eye following the attack in Temple Bar in April 2012.

Mr Russell and his brother Patrick were targeted after they intervened to try to stop a robbery.

They were chased down the quays and attacked with glass bottles.

Garth Russell was not in court yesterday, but in a statement last night the New York stockbroker said what happened was far from what he expected from his trip to Dublin.

During sentencing, Judge Patrick McCartan said the juvenile justice system did not seem capable of dealing with the men at the centre of this case.

Echoing the judge’s comments, Mr Russell said that the number of previous encounters his attackers had with the law was troubling.

However, he praised the work of gardaí in tracking down the gang and said he wants to put the experience behind him.
