A teenage girl and a man being questioned by detectives investigating the murder of Daniel McAnaspie have been released without charge.
Three other men quizzed in relation to the case were also earlier freed from custody.
A garda spokesman said files were being prepared for the Director of Public Prosecutions.
Daniel, who was in Health Service Executive care, vanished after socialising with a group of people in Blanchardstown on February 25.
The 17-year-old's body was found dumped in a ditch on farm land in Co Meath on May 13. He died of multiple stab wounds.Reuse content
