A 28-YEAR-OLD man has been arrested about the murder of Colin Horner who was shot dead in the car park of a Co Down supermarket on Sunday.
The man was taken Musgrave PSNI station for questioning yesterday evening.
Meanwhile, George Gilmore Jnr, whose father Geordie Gilmore was shot dead by the same loyalist faction in March, has described the latest victim of UDA infighting , as "a superhero family man".
Police have appealed for information about the gunman who shot dead the 35-year-old in front of horrified shoppers in Bangor and his three year- old son who was in the car at the time.
The Irish News revealed yesterday that the suspected gunman is currently on bail for other paramilitary offences and was wearing an electronic tag at the time of the shooting.
Mr Horner had been living with his girlfriend in Bangor after leaving Carrickfergus and then later an address in Ballysillan in north Belfast, amid threats from members of the south east Antrim UDA.
A close friend of former UDA commander Geordie Gilmore, who was also shot dead by the same ruthless rival faction, he was one of more than 60 people who to have received death threats.
The feud has been simmering since June last year when a gang of around 100 men marched to the Gilmore home in Carrickfergus in an attempt to intimidate him from the town. He was shot and fatally wounded as he sat in his car in March.
Mr Horner had attended the funeral of his former associate against the orders of the UDA and had made several comments about the murder on social media.
However, he was considered a soft target and had not been active within the paramilitary group for some time before he was gunned down in Bangor at the weekend.
Mr Horner's partner also paid tribute to her partner on social media and described the killer as "a little boy, a nobody".
