THE brother of a murdered pizza delivery man has been left with serious injuries in a stabbing incident at a house Crumlin in which another man was killed.
The murder victim, named as Niall Magee, was taken to hospital after police received reports of a "serious incident" at Cairn Walk in the Co Antrim town in the early hours of Saturday.
The 21-year-old died from his injuries yesterday morning.
The mother of a second man injured in the incident said she was horrified by news of the stabbing.
Sally McManus, whose son Kieran (26) was shot dead outside Domino's Pizza close to Kennedy Way in March 2013, said her son Michael (25) was in hospital with serious injuries to his eyes and face.
She said she "couldn't believe it" when told of a violent incident involving another son.
Kieran's death was linked to a bloody feud in west Belfast dating back almost a decade which also claimed the life of a father-of-one.
Stephen Carson (28) was shot dead at his Walmer Street home in south Belfast in February 2016.
Two cousins Michael Smith (40) and David Smith (34), from west Belfast, were convicted of the murder.
It is believed the killings were linked to an altercation in Turf Lodge in 2010 which saw Michael Smith almost lose an arm in a samurai sword attack.
The feud has also been linked to intimidation which has seen several people flee their homes.
It is not known if this latest incident is linked.
Police, who have launched a murder inquiry, have arrested four men aged 19, 24, 25 and 29.
