One of the ones found has been linked to Horeston Grange.
Officers in Bedworth are appealing for information as part of an investigation into the suspected theft of defibrillators.
In march two defibrillators were stolen from Bulkington and Horeston Grange in Nuneaton.
Now officers working on this case have identified 11 of the life-saving devices that they believe a suspect sold online earlier in the year.
One of these has been linked via the serial number to the theft from Horeston Grange.
They are now trying to establish whether the other 10 were stolen and are appealing to anyone else in the surrounding area who is missing a defibrillator to get in touch quoting incident 169 of 30 March 2022.
