Please take the time to read the following crime prevention advice, and please share this with professional groups and contacts you may have, especially if you are a self-employed tradesperson in the areas affected:
Wherever possible remove your tools from your vehicle and store securely overnight.
Mark the tools clearly with your name/company name and address using paint pens and seal with a clear lacquer spray. Other property marking systems are available.
Consider using smart/GPS tags on high value items to enable them to be tracked.
Use a lockable cabinet within your van to store the tools during the day.
Use a small camera designed to record within vehicles.
Take photographs of items of value, making a note of the serial numbers and registering them online at a property register site.
