Gardaí are appealing for witnesses after a motorcyclist was seriously injured in what investigators believe may have been a hit-and-run in Dublin city centre.

The incident happened on Amiens Street near the junction of Store Street at around 10:20pm last Thursday May 9th.

Gardaí said the motorcyclists, a 27-year-old man from the Fairview area, received serious injuries when he was struck by a car.

He was treated at the scene by emergency services before being removed to the Mater Hospital where he is receiving ongoing treatment for multiple injuries.

Investigators said they understand from their inquiries that his bike might have been hit from behind by a dark saloon-type car while travelling out of the city.

The car failed to remain at the scene.

This evening Gardaí issued an appeal to anyone who may have witnessed the incident to come forward. They are particularly interested in talking to any motorists who may have dash cam footage of the incident.

Anyone with information is asked to contact Store Street Garda Station.
