A man has been released from custody as gardai continue to investigate the brutal killing of a Drogheda teenager in January 2020.
The man was arrested and detained at Drogheda Garda Station on Wednesday.
He has since been released without charge.
A gardai spokesman said: "A file will be prepared for the Director of Public Prosecutions."
The teenager cannot be named due to a recent decision of the Court of Appeal which states minors who are victims of crime cannot be identified, even if they are deceased.
New laws introduced by the court of repeal under section 252 (1) of the Children Act, 2001 states: "In relation to any proceedings for an offence against a child or where a child is a witness in any such proceedings, no report which reveals the name, address or school of the child or includes any particulars likely to lead to his or her identification' and 'no picture which purports to be or include a picture of the child or which is likely to lead to his or her identification' shall be published or included in a broadcast."
