Police show CCTV in bid to piece together last hours of William McCormick in Belfast - two further arrests
Security camera footage showing the last known movements of a missing Co Down father-of-four who police believe was murdered has been released by detectives.
The short clip shows 55-year-old William McCormick, known locally as Pat, driving his car on Castle Street in Comber at around 10.30pm last Thursday.
The footage then shows him walking down Castle Street at 10.45pm, when he goes under an archway that leads to flats.
On Wednesday evening police made a further two arrests. A 39-year-old man and a 20-year-old man were detained on suspicion of assisting offenders and pervert the course of justice. They were taken to Musgrave police station for questioning.
Police also believe a missing iPhone could prove crucial to the murder probe.
The footage was released by detectives from the PSNI's major investigation team in a new appeal for information.
Detective Chief Inspector Pete Montgomery explained the investigation was changed from a missing persons inquiry to a murder inquiry after a review of information and evidence.
Mr Montgomery said: "I know that Pat left his parents' house in Ballynahinch on Thursday, May 30, just after 9pm.
"In the CCTV Pat can be seen driving his car in Castle Street, Comber, at around 10.30pm. It's a Black Citroen C4, registration BSZ 7103.
"I know Pat parked his car on High Street, opposite McBride's pub, where it remained until it was recovered by police.
"In the footage Pat can be seen walking down Castle Street at around 10.45pm, (when) he goes under an archway that leads to some flats. This is the last sighting that I have.
"On the night of Pat's disappearance, he was wearing a beige jacket, blue jeans and brown brogue shoes.
"He had short, dark brown hair. He was 5ft 3in in height and of medium build.
"We are now six days on from Pat's disappearance and his family deserve to know what happened to him. I'm hoping that the release of this footage will jog people's memories."
Mr Montgomery also urged people to report any discarded clothing to detectives and to be on the lookout for an iPhone SE.
He added: "Pat's phone hasn't been used from May 30 and it remains unaccounted for. It's an iPhone SE, so if you're out and about and see it lying somewhere, let me know. It could be broken, smashed or in pieces.
"I have met with Pat's wife and parents and they are devastated.
"His mother and father are in their 80s and they deserve to get his body back.
"Members of the local community could have information that could be key to giving Pat's family some answers.
"I would urge anyone who has any information surrounding Pat's disappearance to contact detectives at the incident room at Musgrave Street (police station) on 101."
Information can also be provided to the independent charity Crimestoppers on 0800 555 111, which is 100% anonymous and gives people the power to speak up and stop crime.
A 26-year-old man and 20-year-old woman who were rearrested on suspicion of murder on Monday evening remain in police custody, being questioned by detectives.
