The life saving device, which is worth £1000, was taken sometime between Monday 15 and Saturday 20 January from its site in the alleyway next to Watson’s Grocers in High Street, Moniaive.
Police are investigating and Constable Lee Smith said: “It is beyond belief that someone would steal such a piece of equipment, put into the community with the purpose of saving life. I am appealing to anyone who has any knowledge of this theft to get in touch with us through the 101 number, quoting PDG0014650118, or if anyone wishes to remain anonymous, then through Crimestoppers on 0800 555 111.”
