GARDAI believe that these three people have important information about a savage assault in Dublin city centre which resulted in a 16-year-old youth suffering a broken jaw.
Our CCTV images show three people -- two young men and a young woman -- who were present when the unprovoked attack happened. The man in the orange T-shirt is the alleged attacker.
Officers from Pearse Street Garda Station in Dublin have launched a fresh appeal for information about the shocking assault which happened at 8pm on the night of May 3, 2009.
The teenage victim, who is from Dublin, was left with horrific injuries and severely traumatised after being attacked by one man whose friends then helped the victim as he lay on the ground outside Centra in D'Olier Street.
One of the attacker's friends even confronted the suspect after the assault in which the innocent teenager was punched and kicked.The investigation into the incident has been ongoing and gardai have interviewed two people about the assault who later turned out not to be involved in it.
A source explained: "The injured party suffered a broken jaw and has had to have reconstructive surgery as well as regular dental work done. He has suffered some distress since the incident and has suffered psychological affects since.
"Even though this assault happened over three years ago, the investigation remains open and a new investigation team is now looking at. We would appeal for anyone with any information to contact gardai."
Anyone with information is asked to contact Pearse Street Garda Station at 01 6669000, the garda confidential line at or the Garda Confidential Line 1800 666111 or any garda station.
