A fire which destroyed hay bales worth £30,000 has left a farmer "considerably out of pocket", the police have said.
The incident, described as a "reckless act" by the police, occurred at Adniston Farm, in Macmerry, around 7.30pm on Wednesday (17 October).
It is thought that around 1,000 hay bales were destroyed in the suspicious blaze.
Detective sergeant Jamie Gilmore said: "Whoever was responsible for this reckless act has left the farmer considerably out of pocket by completely destroying a large quantity of hay that was used either to feed livestock, or to be sold on.
