Police are appealing for help to find those responsible for deliberately injuring three kangaroos at Muswellbrook.

Officers were called to Wollombi Park around 8.00am on Sunday where a bushwalker found the roos seriously injured in scrubland.

Police say initial inquiries suggest two of the roos may have been deliberately run over a by a vehicle while a third kangaroo, which was found deceased, had suffered a wound to the chest.

It’s believed the other two roos have since died.

Investigators are appealing for anyone with dashcam footage in the area at the time to contact Crime Stoppers on 1800 333 000.
