Police are urging farmers to be vigilant after a spate of thefts in recent weeks.
Farms in the Dyke area of Forres and Deskford area of Buckie were targeted between Monday evening and Wednesday morning whereby a number of tools, animal feed and weedkiller worth almost £4,000 were stolen.
It came just days after police revealed herbicides worth about £10,000 had been stolen from a farm in the Westerton area of Meikle Wartle near Inverurie between May 17 and May 25.
As part of ongoing inquiries, officers in the north-east have been liaising with officers in the Highlands and Islands following a similar incident at a farm near Munlochy on the Black Isle.
A quantity of agricultural chemicals, including fungicides and herbicides, along with a tractor GPS system were taken after entry was forced to a storage building between Thursday, May 23 and Friday, May 24.
PC Jamie Barclay said: “To have so many similar thefts take place in the region in such a short space of time is extremely rare and therefore very concerning. Rural communities are generally very safe places in which to live and work however the nature of the environment and way of life means that visible security measures can be essential if you want to prevent crime.”
