Two 18-year-old men are due to appear at Dublin District Court tomorrow morning charged in connection with a serious attack on a 48-year-old Lithuanian man.
A third teenager has been arrested in connection with the incident, which took place along the Royal Canal in Dublin last night.
Gardaí say the man was set upon by up a gang of youths and beaten about the head and neck.
His condition is described as critical at Dublin's Mater Hospital.
Gardaí are trying to establish a motive for the attack and are appealing for anyone who was in the Drumcondra area last night to come forward.
