An investigation is under way into the theft of more than 180 sheep from a property in Tungamah last month.
Cobram Crime Investigation Unit detectives were told 181 Suffolk/Merino cross lambs were discovered missing from a Lawrence Rd property sometime between September 22 and December 20 last year.
The sheep, which were part of a larger flock, had been in the vicinity of Youarang, Walden and School Rds, according to police.
They had been shorn on September 22 before being put in the paddocks, however, it was discovered some were missing after they were counted on December 20.
It was initially thought the lambs may have escaped from the paddocks but police believe they were deliberately taken from the property by unknown offenders.
Police have released an image of some of the lambs in the flock in the hope someone may have information.
The livestock all had orange ear tags before being taken.
■Anyone with information on the theft or the whereabouts of the sheep is urged to phone Crime Stoppers on 1800 333 000 or submit a confidential report online at: www.crimestoppersvic.com.au
