Thames Valley Police arrested a man on Sunday (2/2) on suspicion of handling stolen goods.
This follows reports of the sale of numerous tools at a local car boot sale. The location has not been announced.
Members of the public took to Facebook last week to share concern about alleged tools with initials on being sold at the MK Bowl Market and Car Boot Sale. It is not yet known if this is linked.
Thames Valley Police said: "Officers are keen to try to reunite the owners of these tools with their property and are asking for victims of thefts of drills or similar tools to make contact with the investigating officer. At this time, we are particularly keen to hear from owners of DEWALT and MAKITA drills that have been stolen.
"If you believe that your missing items may be amongst the items we have recovered, please contact 101 and quote reference 43200037061 ensuring that you have the serial numbers of the items available or any other clearly identifiable marks or features and proof of ownership.
"We will not be able to reunite any owners with their tools without this information and to prevent false claims on these expensive tools, we will not be publishing photos of the items at this time. If you believe that we may have your tools, please make contact and officers will be in contact."
The man has been interviewed and enquiries are ongoing.
