Detectives believe that a “spotter” gave information to a gunman who shot dead a father of three in a Dublin pub exactly a month ago.

Gardaí are renewing their appeal for information following the shooting death of a 36-year-old man in Dublin last month.

INNOCENT plumber Anthony Campbell, who was gunned down while at work in a north Dublin house, had both arms raised in a defensive posture when he was murdered, the findings of a postmortem suggest.
