FAMILY members of a multiple stab victim rushed out of a courtroom in tears as footage was shown of the teenager being chased to his death.
A Central Criminal Court jury was shown the CCTV footage during the trial of another teenager, who is charged with murdering the 19-year-old almost two years ago.
David Byrne was stabbed to death, after being chased into a dead end at Emmet Court apartment complex in Inchicore, Dublin on the night of March 19, 2011.
Marcus Kirwan (19), of Cooley Road, Drimnagh has pleaded not guilty to murdering Mr Byrne, who lived at Davitt House, also in Drimnagh.
Garda Ciaran Byrne of Kevin Street Garda Station showed the jury about 45 minutes of CCTV footage from that night, captured by a number of cameras in Drimnagh and Inchicore.
Some members of Mr Byrne's family cried and left the court as a person was shown being chased by others near St John Bosco Youth Centre in Drimnagh.
There were more emotional scenes as the chase was shown continuing across the Luas tracks to Inchicore at around 10.30pm.
A person was then seen running into the Emmet Court complex, with another person a few metres behind him. They both disappeared off camera before a third and then a fourth person ran into the complex.
The third and fourth people then left, followed by the second person.
A close-up and slowed-down shot of their backs was shown, in which the second person looked behind him.
Another camera then showed a person stagger into shot before falling to the ground.
The trial has already heard that Mr Byrne died of multiple stab wounds later that night.
He sustained nine wounds in all.
Mr Justice Garrett Sheehan has told the jury of seven men and five women that the CCTV evidence will continue on Monday.
