Two people have been charged with the murder of a 50-year-old man.
Mark Dorrian was found unconscious in a flat in Newtownards, County Down, in the early hours of Boxing Day.
He had sustained a number of injuries, including head injuries, and later died in hospital.
A woman, 33, and a man, 36, have both been charged with his murder and are set to appear in court on Monday.
They had been arrested previously along with a 58-year-old woman who has now been released unconditionally, the Police Service of Northern Ireland (PSNI) said.
Speaking on Friday, Detective Chief Inspector Neil McGuinness said: “A murder investigation was launched after a report was received that a man was unconscious inside a flat in the West Street area, just before 1.50am on Thursday, 26th December.
“Mark sadly died later in hospital having sustained a number of injuries, including head injuries. A post-mortem examination will take place in due course.”
