A well-known dissident republican has died after he was shot in Finglas, Dublin.

25-year-old Vincent Ryan was shot on McKee Road. 

He was taken to the Mater Hospital where he was later pronounced dead.

Gardaí said Ryan was shot while sitting in his car, a white Volkswagen Golf.

They said he was approached by someone driving a silver or grey Volkswagen Golf at around 3.15pm.

After a number of shots were fired, the car left the scene in the direction of Clune Road and Jamestown Road.

Ryan is well known to gardaí for his involvement in dissident republican activities.

He was charged before the Special Criminal Court a few years ago with possession of a rifle and handgun - but was subsequently acquitted.

He had also been warned that his life was in danger and a close relative of his - also involved in dissident republican activity - was shot dead.

Superintendent John Quirke from Finglas Garda Station appealed for anyone who may have been in the McKee road area or may have any information to contact gardaí.

He also appealed for anyone with information regarding a burnt out car found in the Victoria Bridge area on the Naas to Rathangan Road, which may have been involved in the incident, to contact them.
