A MOTORCYCLIST has died following a two-vehicle collision in Dublin.
The incident occurred on the Sallyglen Road in Glenegeary at around 8.15pm on Friday.

In the Dublin incident, gardaí said the male motorcyclist, aged in his 50s, was fatally injured when his vehicle was involved in a collision with a car.

The road was closed while a technical examination was conducted by Garda Forensic Collision Investigators.
Gardaí have now appealed to anyone who may have witnessed the incident to contact them.
Road users who may have camera footage and were travelling on the Sallyglen Road at Glenageary between 8pm and 8.30pm on Friday are asked to make the footage available to gardaí.
