A grandfather who was killed in Northern Ireland in an attack reportedly linked to the attempted murder of a priest has been described as a 'beloved father and grandfather'.

The body of Stephen Brannigan, who was in his 50s, was found in a house in Marian Park in Downpatrick on Sunday afternoon.

Police are investigating if his death is linked to an attack on a priest in the town, Father John Murray.

Fr Murray was rushed to hospital after he was 'bottled by a man who walked into church before mass'.

He was hit on the head at St Patrick's Church in Downpatrick on Sunday.
