A 34-year-old man has been arrested in connection with the murder of a pizza delivery driver.
The suspect was detained by detectives from the PSNI's serious crime branch, which is investigating the weekend killing of Kieran McManus.
The 26-year-old was shot dead outside Domino's Pizza at Kennedy Way on Saturday night.
Police said the suspect was arrested in Belfast yesterday and had been taken to Antrim serious crime suite for questioning.
Yesterday Mr McManus's mother branded his killers as cowards.
Sally McManus said she wanted to confront the gunman who had torn the heart out of her family.
She said: "I would really love to meet the one that pulled that trigger. It was real big of them shooting him in the back.
"It has just ripped the heart out of us. As for me, I don't know how I'm going to get through it at all until these people are brought to justice."
Mr McManus, a father-of-one, who was known to police, was hit a number of times as he chatted with friends on Saturday night.
He had been working as a delivery driver for the Domino's Pizza establishment on Kennedy Way when he was shot.
He had previously faced attempted murder charges over his role in an attack on another man in west Belfast.
Police have described the killing as brutal and said they are keeping an open mind about the motive. It is thought the gunman called his victim by name.
A red Vauxhall Astra was found burnt-out a short distance from the murder scene.
Mrs McManus said: "At first I thought he had got shot in the legs or something, but shot in the back? That's just cowardice. That is just cold-blooded murder.
"It is a mother's worst nightmare – especially as it (the murder) was the most cowardly way."
Mrs McManus has appealed for anyone with information to come forward: "Kieran was a genuine, lovely fella.
"He got into some bother a few years back when Kieran stood up to these people," she told Radio Ulster's Nolan Show.
"Kieran was a qualified youth worker. Kieran helped the community, he didn't torture it.
"He wasn't anti-social at all. There were no threats made towards Kieran from dissidents and he wasn't on no hit-list – the police confirmed that for me.
"He loved life and was completely focused on his wee boy. Now that wee child has to grow up without a father. I just hope those people are proud of themselves."
