A gold and black Seadoo jet ski, valued at £5000, was stolen from a garage in St Ninians Crescent, Whithorn sometime on Wednesday evening.
Thieves also made off with a green KXD child’s mini moto 50cc dirt bike, valued at £250, and £200 worth of children’s toys which had been bought as Christmas presents.
Meanwhile, a red Honda quad bike, valued at £3000, was stolen from a shed at Midbishopton Farm, also Whithorn, on the same night.
And another Honda quad bike stolen from Lowbishopton Farm, Whithorn, at the same time was later found abandoned at the Old Piggery – approximately a quarter of a mile from where it was taken.
Attempts had also been made to break into a shipping container at the Old Piggery but no entry was gained.
Detective Constable Andrew Santangeli said: “There certainly appears to have been a lot of criminal activity in and around the Bishopton area of Whithorn overnight on Wednesday into Thursday.
“We have reports of two vans, a bright red Ford Escort style and a white Ford Transit style, being seen in the area in the early hours of Thursday morning.”
He added: “We want to hear from anyone who may have seen these vans, or indeed can assist us with this enquiry.
“This has all the hallmarks of a well-planned crime spree which has cost the victims many thousands of pounds.”
Anyone with any information should contact police on 101.
