Rural crime investigators have been called in to find who is behind the disappearance of 75 sheep from a property on the Reedy Creek Road, Guyra.
The mixed sex merino ewes and wethers were part of a mob of 307 and the loss was discovered early in November.
The sheep are about four years old and were freshly off shears at the time they went missing.
They have yellow, orange or green coloured ear tags, police said.
Investigators from the Rural Crime Prevention Team at Inverell said they were keen to speak with anyone who may be able to assist with any information in relation to the missing sheep.
They’re also appealing for anyone seen acting suspiciously in or around the Old Armidale Road and Reedy Creek Road area, west of Guyra.
Police are also urging landholders to report stock theft swiftly, regardless if it is a small number of stock.
Police are urging anyone with information in relation to this incident to rural crime investigators at Inverell on 67220530/31.
