Police are investigating six burglaries since the start of the month where garden sheds have been broken into, and in several instances, expensive power tools stolen.

A West Mercia Police spokesperson said: “We want local people to be aware of what’s happening and to do everything possible to tighten up on security.

“Most of the sheds were locked and their doors were forced open, but in several cases doors had been left unlocked.”

Three of the burglaries were on neighbouring properties in Bryn Melyn, Llynclys. Nothing was stolen at two of the addresses but various garden ornaments were taken from the other.

Thieves made off with a pressure washer from a shed at Llanymynech while a chainsaw and hedge trimmer were taken from an address in Sweeney.

In another incident, a petrol strimmer was stolen from a shed in the back garden of a house at Pant.

Police are advising the public to be vigilant and to report any suspicious people or vehicles by dialling 101. “Any car that is not familiar to residents and appears to be ‘hanging around’ should be reported to police so it can be checked out,” said the spokesperson.

“The same goes for any people you do not recognise and who seem to be acting suspiciously in your street. In an emergency or if there is a crime in progress, always dial 999”.

There are several simple steps gardeners and householders can take to protect their property against burglars. Most sheds are not designed for secure storage but it’s possible to make it much more difficult for burglars to get inside.

Make access to your shed or garage difficult by locking gates and planting thorny bushes alongside walls and fences. External lighting with movement sensors is also an effective deterrent, as is a shed or garage alarm.

Mark the contents of your shed with your postcode and house number, either visibly or with a UV pen or other property-marking system. Make a note of serial numbers and photograph valuable items and ornaments.

Use strong coach bolts (dome heads) or non-return screws to secure door hinges and consider fitting a specialist lock. Fit grilles across windows and use robust, closed-shackled padlocks and strong hasps and staples resistant to cutting.

Wherever possible, keep valuable tools in the house. Never leave tools or items such as ladders out, where they can be used against your own property.

Chain up cycles, mowers, ladders and large tools and consider using specialist tool holders and clamps.

Finally, check that your home insurance covers the contents of a shed or garage. For more information and advice, visit the West Mercia Police advice centre on http://www.westmercia.police.uk/ .
