Police have issued crime prevention advice following a number of commercial burglaries.

Purbeck Police said they had received a number of reports over the summer. Anyone who witnesses suspicious activity is urged to call officers on 101.

Advice includes:

* Choose an alarm from a professional alarm installer

* Make sure locks on doors are up to insurance standard

* Make sure there are locks on windows and that they are locked at night

* Leave tills empty and open to deter thieves looking through the window

* Fix safes to a concrete floor or brick wall and hide it

* Ensure CCTV is fitted correctly and has the right lighting or infrared facility. It must be monitored 24 hours a day.
