An elderly woman has died after the Welsh ambulance service took almost two hours to reach the scene of a serious car crash in Llanrwst.
The woman, who has not been named, was airlifted to hospital after a two-vehicle crash on the A470 on September 19.
She died two days later.
The incident which occurred just after 3 p.m. involved three other people who were injured as the road was closed for almost eight hours.
An ambulance had been called at 3:12 p.m., but the first to arrive at the scene arrived at 5:00 p.m., with a second at 5:30 p.m.
The service said the incident was “classified as a serious but not immediately fatal call.”
However, a passerby who stopped by the accident to help, said it was “distressing” and “frustrating” that the ambulance service had taken so long to reach.
Charles Owen also said: “There were six police cars at the scene, but what was needed were ambulances. It was a horrible situation and it’s so sad to hear that the poor lady is dead.
“We kept hearing sirens in the distance thinking, hoping it was an ambulance, but it never was. It is very sad and unacceptable that the ambulance service has come to this.”
Janet Finch-Saunders, Aberconwy AM said: “This is outrageous, my thoughts are with the family and friends of this poor lady.
“Lives are now being lost and I am shocked to hear what happened in this tragic incident.
“The ambulance service is now called because people can’t even see their GP. It’s awful right now and I brought it up as a debate in the Senedd.”
Stephen Sheldon, of the Welsh Ambulance Service in North West Wales, said: “We received a call at 3.12pm on Sunday 19 September to report a traffic accident between two vehicles in Llanrwst, which was classified as a serious but not immediately life threatening call.
“We dispatched two ambulances and an air ambulance, with the first resource arriving about an hour after the call.
“We want to better understand the concerns of those affected and invite patients or their representatives to contact the Trust so that we can communicate with them directly. “
A blue Mazda 6 and a black Peugeot 208 were involved in the accident.
Anyone who may have witnessed the incident or who has onboard camera footage that could aid the investigation is urged to contact police on 101 quoting incident number Z138698.
