Thousands of pounds worth of power tools have been stolen during a spate of van break-ins across the Vale over the festive holidays.
Detectives say at least ten thefts have been reported in the last three weeks, mainly in the Penarth and Barry areas at night.
South Wales Police are urging vehicle owners to be vigilant while their investigation continues.
A force spokesperson said: "Thieves steal power tools and often attempt to sell them on, with no regard for the livelihood of those they have stolen from."
"Please be vigilant to this kind of crime. While enquiries continue to identify those responsible, please take extra precautions to protect your property and report any suspicious activity."
Anyone with information about the thefts should contact South Wales Police on 101 and via the live web chat or Crimestoppers anonymously on 0800 555 111.
