POLICE are warning van owners to be vigilant when leaving tools inside their vehicles after a spate of thefts.

Thirty-three such thefts were reported to police in Stockton between April 1 and August 31 - however, 11 of those occurred last month.

Stockton police's crime reduction officer PC Dave Sanders warned: "Don't let your van be the next target - take a few simple measures to reduce the opportunities for the thief."

He said straight-forward steps could be taken, including:

* Fit good-quality locks and an alarm to the vehicle;

* Always leave the vehicle locked, even when going back and forth to the vehicle for tools etc;

* Do not leave tools in the vehicle overnight;

* Signs should be placed on the vehicle stating no tools are left overnight;

* Make sure access cannot be gained to the storage area from the cab by fitting a partition in the vehicle;

* Fit internal grilles to any rear windows

* All tools should be visibly marked for identification, and makes, model and serial numbers should be recorded.
