A 20-year-old was stabbed to death after he called his teenage murderer a "rat" during a drug-related row, the Central Criminal Court has heard.

The 17-year-old defendant, who cannot be named because he is a minor, pleaded guilty last month to the murder of Glen 'Ossie' Osborne, 20, at Ballybough House, Ballybough, Dublin on April 15 this year.
