Three men are still being questioned in Belfast in relation to the murder of a Dublin gangland criminal.
The PSNI expects to have the identification process finished today, but have said they suspect the victim of the lone gunman attack is 36-year-old Robbie Lawlor, from Donaghmede.
Four men, aged between 17 and 33, were arrested on suspicion of murder - but one has been released.
A home in Crumlin has been searched as part of the investigation.
PSNI Detective Superintendent Jason Murphy outlines the line of inquiry.
"I don't believe that Robbie Lawlor was in Ardoyne by accident.
"My belief at this stage is that he had some reason to be there - a key line of enquiry for me and my team is to establish what that reason was.
"At this stage I believe that a single gunman was involved, I believe that multiple shots were fired, and the gun has not yet been recovered."
