Gardai are appealing for witnesses to come forward after a man was brutally attacked by four teenagers on Wednesday afternoon.
The 31-yr-old man was walking through Castle Riada estate in Lucan when he bumped shoulders with one of the gang as they passed.
A verbal row ensued with the four teenagers taking into him with punches and kicks soon after.
The man survived the attack but was left with very serious facial injuries.
Gardai have asked anyone who saw anything to call the confidential line on 1800 66-61-11.
