A woman has died in a two-vehicle crash near Brynsiencyn.
Three people, including a child, have also been injured following the collision between a blue Ford Fusion and a white Ford Focus on the A4080 at just after 3.30pm on Saturday.
Police say the woman, who was driving the Ford Fusion, was pronounced dead at the scene. An 11 year-old child, who was a passenger in the car, was taken to Ysbyty Gwynedd in Bangor with minor injuries.
The male driver of the Ford Focus suffered serious injuries which are not thought to be life threatening – his passenger, a woman, sustained minor injuries. They were both taken to Ysbyty Gwynedd.
The road remained closed for almost five and a half hours while forensic experts examined the scene of the crash. Traffic was diverted via Pentre Berw, Llangaffo and Dwyran.
Officers are appealing for anyone who witnessed the crash to come forward – including anyone who may have dashcam footage.
Sergeant Nicola Grimes-Williams said: ”Our thoughts remain with the family of the woman who died at this difficult time. We are appealing to anybody who may have been travelling along the A4080 at the time of the collision…to please contact us as soon as possible.”
