Watch: Crimewatch Raymond Johnston murder appeal shows two men entering his Belfast home
Newly released CCTV footage shows two men entering the home of a west Belfast man to carry out a 'cold and clinical' murder.
On 13 February, 28-year-old Raymond Johnston was killed in front of his young daughter and partner at his home on Glenbawn Avenue.
For the first time the PSNI has released CCTV images of two suspects caught on camera.
The footage taken outside of Mr Johnston's home shows two hooded men approaching the house at around 7.45pm and making their way inside.
Detective Chief Inspector Geoff Boyce from the Serious Crime Branch said: "One of these men is clearly armed with a weapon. The first male appears to open the door and you can see the second male is carrying what we believe is a long barrelled firearm.
"They go into the home and less than 10 seconds later, the pair emerge having shot Raymond Johnston in the chest, killing him.
"Raymond’s family, his partner and her daughter have been left devastated. Not only did they lose Raymond in the most brutal way, but his partner and her daughter also witnessed his horrific murder.
"The trauma of witnessing such a cold, clinical and calculated killing will be etched in their memories for the rest of their lives. They didn’t deserve this and there is absolutely no justification for murdering Raymond."
CI Boyce said PSNI believe dissident republican terrorist group Arm na Poblachta were directly involved in Mr Johnston's murder.
"The gunmen deliberated, planned and carried out the murder of Raymond Johnston brazenly, coldly and clinically. We need to identify the perpetrators and take them off the streets in order to prevent further murders from taking place," he said.
"I am asking people living in the Glenbawn area to search their memories and consciences. Try to recall where you were on the day before Valentine’s Day - did you see Raymond that Tuesday, did you see the gunmen approach his house?
"We have made arrests and carried out searches as part of this investigation and we are making progress, however I would plead with the community to help us take that next step to unmask these killers.
"No matter how trivial or inconsequential you think a detail might be, please tell us. It could be the missing piece of the jigsaw that helps us solve this savage murder and lead us to those who are responsible."
The public is encouraged to contact police on the non-emergency number 101, or by contacting independent charity Crimestoppers anonymously on 0800 555 111.
