Australian police investigate after man filmed punching kangaroo

Warning: Graphic content.

A video showing a man repeatedly punching a kangaroo has angered people online and prompted an investigation by police.

The vicious attack on the marsupial was filmed and shared on social media, including Snapchat and Facebook.

The attack took place somewhere in New South Wales, according to multiple reports.

It's not clear whether the animal was still alive as a man wearing green shorts punches at the marsupial's face. During the video, a second person, not visible in the footage, can be heard laughing.

It was suggested online that people involved in the attack had hit the kangaroo with their car before filming the attack.

NSW Police told 7 News they are conducting inquiries and are aware of the video.

Video shared on social media shows the man repeatedly punching the animal.
