A DUBLIN man called another man 'a rat' before slashing his head six times with a Stanley knife, it has been claimed.
Sean Farrell (25) is alleged to have left the victim with serious head and facial injuries, including a split ear, following a roadside assault.
The accused was allegedly sitting in the back seat of a car when he held the victim against the front seat and repeatedly stabbed him.
Farrell is facing trial by judge and jury in the circuit court.
Judge Alan Mitchell refused bail and remanded him in custody for two weeks.
The accused, of Castle Park in Tallaght, appeared before Cloverhill District Court charged with assault causing serious bodily harm to another man and with possession of a Stanley knife with intent to cause injury.
The alleged incident took place at Castle Park in Tallaght on June 18.
Detective Garda David Jennings said it will be alleged that the victim drove his silver Mitsubishi Colt into Castle Park at about 8pm to meet a friend.
Farrell allegedly approached the car and asked to get in. He sat in the back behind the victim and called him 'a rat'.
Garda Jennings claimed the accused then took out a knife, held the victim against the front seat and repeatedly stabbed his neck and face.
The detective also alleged that Farrell cut the man's right ear open.
The court heard the victim received four slash wounds. Garda Jennings alleged he had wounds on each side of his face and his right ear was slit open.
The garda said the victim managed to get out of the car with the assistance of his friend.
The victim was taken by ambulance to Tallaght Hospital where he was treated for his injuries.
Garda Jennings further claimed that, when he was questioned about the assault, Farrell told officers the injured party would be "chopped up" when he was released.
The garda also alleged that forensic evidence links the accused to the assault.
Defence solicitor Danny Nolan said Farrell, who is not working, was willing to abide by any bail conditions.
