An ambulance was stolen while a crew were treating a patient at their home address.
The vehicle was taken while on a call in the Shotton area, near Chester, on Saturday (November 14).
Another vehicle was dispatched without delay to assist the crew, reported North Wales Live.
Police later found the stolen ambulance damaged and abandoned on Dee View, Shotton.
Bob Tooby, Assistant Director of Operations at the Welsh Ambulance Service said: "The theft of an emergency ambulance is an extremely irresponsible act placing patients and the public at risk.
"Had the crew needed to access additional emergency equipment from the vehicle, or to urgently convey the patient to hospital, this act could have led to very serious harm."
He added: "North Wales Police are now leading enquiries to identify the offenders and we would encourage members of the public to come forward with any information regarding the theft.

"North Wales Police have dispatched their crime scene examiners who will forensically examine the vehicle.
“Our services have been extremely busy dealing with winter pressures, alongside the challenges of the pandemic.
"We will be supporting our North Wales Police colleagues to find the person responsible, and bring them to justice. This is a very rare occurrence but is being treated incredibly seriously."
