The scene of Saturday night's crash on Shamrock Road.

A man was in critical condition in hospital following a three-vehicle collision on Shamrock Road Saturday night.

The victim, who had to be cut free from his vehicle by emergency crews, suffered serious, potentially life-threatening injuries, in the crash around 8.30pm.

One of the drivers involved in the collision, a 31-year-old man, was arrested on suspicion of DUI and later bailed as the investigation continues.

Police closed off the road to traffic between Valley Drive and Will T Drive overnight to preserve the scene for accident reconstruction to take place.

The roadway was re-opened Sunday.
