Police are urging businesses and commercial properties to be on their guard after a spate of thefts.

Over the last two weeks, a number of thefts have taken place at commercial premises in Pembrokeshire during the night.

In particular, isolated premises with outdoor storage are being targeted.

The thieves are also breaking into premises and taking cash and safes.

Businesses are being advised to:

• Remove any cash from their offices and to put up signs to say that all cash has been removed

• Remove any vehicle keys from the premises

• Look at installing further lighting

• Consider getting CCTV; if CCTV is in place, secure it so the thieves cannot access it easily.

DS Paul Callard said: "We are also urging businesses to speak to each other regarding security and looking out for each other.

"Also, if anyone sees anything unusual, particularly during the night relating to a business, we are urging them to contact us on 0845 330 2000."
