Warning over Telford cable exchange box damage
More than 10 cable exchange boxes have been damaged or been the scene of thefts over a fortnight in Shropshire.
West Mercia Police believe boxes in the Telford area are being targeted for batteries which can be found inside and sold on.
It warned anyone breaking into a box was "putting themselves in danger".
Police said damaging boxes could cause disruption to services provided to residents.
One theft happened at about 00:30 BST on Tuesday on Cooke Drive, Telford.
A member of the public called police to report a youth in his late teens, wearing a grey hooded top and black tracksuit bottoms, had used a tool to force open an exchange unit and a number of batteries were taken.
Officers found batteries discarded in nearby bushes and later discovered boxes on Burlington Close and Hinkshay Road, Dawley, had also been forced open and batteries taken.
The force said it was aware there had been reports of similar incidents in Wolverhampton and Walsall.
