A father's life was saved by two hero off-duty police officers after he suffered a cardiac arrest at the wheel of his car.
John Walker, 69, was dragged unconscious from his vehicle and placed into the middle of a busy road where lifesaving CPR was performed by the strangers.
Armed police were called to block the street to allow a third "angel" - off-duty nurse Sarah Watson - to also administer the first aid until an ambulance arrived to dash John to hospital.
