POLICE are hunting a group of kangaroo killers after an adult roo was severely mutilated and tied to a barbed wire fence in a Victorian town.

Investigators believe a number of offenders captured and killed the mature-sized kangaroo in the vicinity of Hamptons Lane and Parkinsons Road in Napoleons, about 130km west of Melbourne, about 1am.

The kangaroo was then tied to a barbed wire fence and was visible from the road.

The police members who attended the scene called on some local residents to help remove the large kangaroo from the fence.

Police would like to speak with anyone who may have heard or seen anything suspicious in the area overnight.
