Three people remain in custody on suspicion of murder after the death of a man in Co Down.
Mark Dorrian, 50, was found unconscious in a flat in Newtownards just before 2am yesterday morning.
Mr Dorrian sustained a number of injuries including head injuries. He was taken to hospital but died a short time later.
A post-mortem examination is set to take place later.
Two women, aged 58 and 33, were arrested at the scene in the West Street area of the town. A man, aged 36, was arrested in a nearby property.
All three were arrested on suspicion of murder.
"They all remain in police custody at this time, with detectives being granted a 36-hour extension to question them this afternoon" said PSNI Detective Chief Inspector Neil McGuinness.
In a statement, DCI McGuinness urged witnesses to come forward, saying that any information may help their murder investigation.
