The Central Criminal Court has heard that an 18-year-old Dublin man accused of stabbing a student to death told arresting gardaí 'I did it'.
Finn Colclough of Waterloo Road, Dublin 4 denies the murder of Sean Nolan on May 26 2007.
Gardaí from Donnybrook, who were called to the scene at Waterloo Road, told the court that friends of the deceased said he had been stabbed by a man who had gone back inside the house.
The gardaí said they met Finn Colclough in the kitchen of the house where he told them 'I did it'.
After being cautioned by gardaí he said, 'he hit me. He wouldn't get out of the garden. I'm only 17'.
Gardaí said Finn Colclough was polite at all times after his arrest and was nervous when he arrived at the garda station.
Earlier Bernie Stenson, an A&E nurse manager at St Vincents Hospital, described how extensive efforts to recussitate Sean Nolan were unsucessful after he was brought by ambulance to the hospital.
Forensic scientist Dr Stephen Dolan told the court he found minute blood stains on a jacket owned by Finn Colclough.
He also examined clothes worn by Sean Nolan on the night he died and found small tears, consistent with a knife cut.
Earlier Sean Nolan's friend Eric Treacy told the court that as Mr Nolan lay on the ground outside Mr Colclough's home, Mr Colcough told them to 'call an ambulance for him' and then went back inside his house.
Mr Treacy said the accused had been shouting at them in an aggressive manner, telling them to get away from his home when he emerged from the house with one or two knives.
He said Mr Nolan had squared up to Mr Colclough and fell back after a scuffle saying he had been stabbed.
Mr Treacy said he tried to stop the blood coming from Mr Nolan's chest and then tried to flag down passing cars, but no one would stop.
He told defence counsel Patrick Gageby that he could think of no reason why those in the house at Waterloo Road would have been anxious about their presence outside the house.
Mr Treacy said they had stood outside and were trying to wave to people inside to get their attention in order to ask for a loan of a cork screw.
He said Mr Colclough had acted completely differently to when they met him on the street earlier when the encounter was friendly.
Another witness, Ciaran Wogan, agreed with defence counsel that Mr Colclough was shouting and waving the knife in a random manner both before and after Mr Nolan had fallen to the ground.
The trial has been adjourned to Tuesday afternoon.
