A 28 year old man has appeared in court charged with the murder of Colin Horner in Bangor.
Alan Wilson from the Ballyrainey Road in Newtownards denies killing the loyalist outside a supermarket on Sunday.
The senior loyalist was shot dead in a Sainsbury's car park as his three-year-old son looked on.
Meanwhile a 45 year old man remains in police custody.
He was arrested in Newtownards this morning in relation to the murder of Colin Horner.
He’s been taken to Musgrave Police Station and is currently assisting police with their enquiries
35 year old, Mr Horner, from Carrickfergus, Co Antrim, recently relocated to Bangor amid fears he would be targeted in the same loyalist paramilitary feud that claimed the life of his friend George Gilmore two months ago.
Loyalist Mr Gilmore, 44, was shot dead in Carrickfergus in March.
On Monday, Detective Superintendent Richard Campbell confirmed a link between Mr Horner's murder and the long-running Carrick feud between rival loyalists was one line of inquiry.
Officers were trawling through CCTV footage from the store car park in a bid to catch the killer.
The detective said the victim had just strapped his son into the back seat of his black Nissan Pulsar car with the registration XFZ 4706, at 2.45pm when the gunman approached and fired at least three shots from a handgun.
