A teenage boy has been killed and five other people have been taken to hospital after two cars collided in Co Cork in the early hours of Saturday morning.
Gardai and emergency services attended the scene of the incident, which occurred around 1am, on the M8 at Ballybeg in Mitchelstown.
A passenger in one of the cars, a teenage boy, suffered fatal injuries in the collision, gardai said.
A teenage boy driving the car and three other passengers, an adult teenager, a teenage girl and a male youth, have been taken to Cork University Hospital to receive treatment for non-life threatening injuries.
A woman aged in her 30s who was driving the other car involved was also taken to Cork University Hospital where she is receiving treatment for serious injuries.
The matter has also been referred to Garda Siochana Ombudsman Commission (GSOC) as one of the cars involved interacted with Gardai before the incident.
The scene remains preserved on Saturday morning to allow for a technical examination, with local diversions in place.
Gardai are appealing to anyone with information to come forward.
