John O’Regan (48), was targeted as he cycled to work in Ballymun at around 8.45am.

The victim, from nearby Barnewall Gardens – originally from Finglas – was not known to gardai for involvement in organised crime, sources said.

He was pronounced dead at the Mater Hospital after the shooting at Gateway Avenue, Ballymun.

He was shot up to six times with a handgun by the lone gunman who fled the scene on foot.

Detectives are probing whether a dangerous Finglas gang are behind the murder as it is believed that Mr O'Regan got involved in a dispute with a senior member of this mob in recent times and felt under threat.

Despite a lack of criminal convictions, sources say that Mr O’Regan was under investigation after gardai seized a shotgun from him which was not licensed to him.

Window cleaning equipment was found near the scene of the capital's latest gun murder and it is understood that Mr O'Regan was on his way to do a job.

Local residents told The Herald that they heard six shots being fired in rapid succession and then heard a scream.
