A CYCLIST was killed after he was struck by a vehicle which failed to stop at the scene near Citywest in Dublin.
The cyclist, aged in his late 30s, was fatally injured after he was thrown from his bicycle on a roundabout near exit three on the M7.
Locals in the area told of how bystanders attempted to perform emergency procedures on the young man, before he was rushed to Tallaght Hospital.
A garda spokesperson said last night the cyclist was pronounced dead shortly after his arrival at the hospital.
The incident occurred shortly after 5pm in rush-hour traffic, as a vehicle was turning onto the M7.
It remains unclear if the death arose from a hit and run incident.
Gardai are also investigating the possibility that the driver of the vehicle was unaware he had collided with the cyclist.
There are a number of industrial estates in the area.
Some workers last night told the Herald they believed the man had been working in one of these and had been making his way home when the incident occurred.
A worker in the local Topaz Garage said: "A woman came in earlier and said that she had seen two people working on a man who had been knocked off his bike.
"There was one person holding up his head while the other person was performing CPR.
"We think he might have worked in one of the offices in the industrial estate but we're not quite sure," the worker added.
Gardai had preserved the area for a technical examination last night.
The road onto the M7 remained closed off, although traffic was moving freely on the motorway.
The bicycle, which had been significantly bent following the collision, remained at the scene and the helmet of the deceased man had been placed on the handle bars.
The lights on the bicycle were still on as gardai diverted traffic from the scene. Officers at Rathcoole garda station are investigating. the incident.
