Police in Northern Ireland are still questioning two men and two women about a murder in which a 29-year-old man was beaten to death, apparently with spades.
The body of Adrian Thompson was found at the back of a house early on New Year's Day at Leamount Park in Banbridge, Co Down.
Yesterday a man and woman arrested in connection with the killing were released without charge. They were arrested along with the four still being held on Friday. Police said those released were no longer suspects.
Police believe Thompson was beaten to death by a gang of people. The killing is not thought to have been sectarian.
