A teenage boy has appeared at the Children's Court in Dublin charged with the murder of a 21-year-old man last year.

Lorcan O'Reilly died after being stabbed at the Oliver Bond House complex in Dublin in the early hours of 1 November, 2015.

A 15-year-old boy was arrested in connection with the murder yesterday morning. 

Detective Sergeant Adrian Whitelaw told the court the accused had nothing to say when charged.

The teenager's mother and grandmother were both in court for the proceedings.

Judge William Hamill said given the seriousness of the charge it would be entirely appropriate for both of the accused's parents to have attended.

The teenager's solicitor said he will contact the boy's father for his next court appearance. An application for legal aid was also made. 

The court was told both of the accused's parents were not working.

The teenager was remanded to the Trinity House Detention Centre and is due before the courts again next Friday.

The boy kissed his mother at the end of the brief hearing before being led away.
