A 42-year-old man questioned about the murder of a 23-year-old in Dublin over the weekend has been released without charge.
Dean Fitzpatrick was pronounced dead after being found suffering from a stab wound outside an apartment complex on the Malahide Rd. in Dublin.
The man was released from custody this afternoon and a file is being prepared for the Director of Public Prosecutions.
Dean was the brother of Amy Fitzpatrick, the Dublin teenager who went missing in Spain in 2008.
