Detectives have arrested a man about a fatal shooting murder in Co Down last week.
Andrew Cully (47) was shot dead in an alleyway at a loyalist housing estate in Newtownards last Wednesday.
He was shot up to 10 times as he sat in his parked car at Beaufort Walk in the West Winds area of the town. The self employed builder lived in the nearby town of Greyabbey.
Detectives revisited the scene yesterday in an appeal for information and have yet to establish a motive for the killing.
