Newtown and Llanidloes police are appealing for anyone with an unregistered defibrillator to get it registered with the Circuit National Defibrillator Network.
In their appeal they said: “Having the defibrillators registered will enable emergency workers to access this vital lifesaving equipment when needed.
“We are aware that there are a number of unregistered defibrillators within our communities and knowing their location, ready status and how to access them can save lives.”
