Gardaí investigating the fatal shooting of a 48-year-old man in Ballymun in Dublin this morning have appealed for witnesses.
John O'Regan, a window cleaner, was cycling to work when he was shot at about 8.45am.
Gardaí said he was approached by a man on a bicycle and shot a number of times in the upper body.
They believe a handgun was used in the attack, but no weapon has been found.
Mr O'Regan, who lived in the area with his wife and child, was taken to the Mater Hospital, but died a short time later.
Gardaí are eager to speak to anyone who saw a man leaving Gateway Avenue on a bike, cycling away from the scene in the direction of Ballymun Road.
They said he was wearing a high visibility jacket and baseball cap, and was cycling on the path.
A post mortem was conducted on Mr O'Regan at Tallaght Hospital this evening.
A garda liaison officer has been assigned to Mr O'Regan's family.
Witnesses or people with information are asked to contact Ballymun Garda Station on 01-6664400, the Garda Confidential Telephone Line on 1800-666-111 or any garda station.
