P-plate driver accused of 'sadistic' act on busy Australian road

An Australian motorist has been left dumb-founded and out outraged after spotting a stingray strung up to the back of a ute by what appears to be fishing line, with the dead animal dragged along a busy highway.

According to the driver who witnessed the scene in Western Australia, and shared a confronting photo of it online, the ute was being driven by a group of "young teens" with the vehicle displaying a P-plate at the time.

"Okay Perth, I've finally seen it all," the driver wrote online on Tuesday, confirming the animal was dead.

"Just cruel," he wrote.

The actions of the ute driver received widespread criticism online and many even urged the local who shared the image to contact the RSPCA and report the sighting, which he later confirmed he did.

"Not technically animal cruelty ... but very disturbing," one person commented.

The teens responsible for the stunt drew heavy criticism online.

"What the f**k is wrong with some people? Who looks at this and thinks it's funny?" one Aussie questioned.

"Absolutely heinous behaviour," another said.

Authorities plead for 'respectful' treatment of wildlife

Rays are closely related to sharks and while certain species are protected, in most areas fishermen are completely free to catch them. Nor are there any minimum size restrictions when catching sting rays but they are subject to a maximum mixed daily taking of three, according to the state fisheries authority.

"While there is no evidence that a WA fishing offence has occurred, Department of Primary Industries and Regional Development (DPIRD) encourages fishers to carefully release all unwanted fish immediately to the water unharmed," a DPIRD spokesperson told Yahoo News. "All retained fish should be dispatched in a considerate and responsible manner. We encourage all fishers to be considerate of other beach users and the community."

After viewing the image shared online, the RSPCA also urged for people to treat all Australian wildlife with compassion.

"RSPCA WA advocates for all animals to be treated in a kind and respectful manner," a spokesperson told Yahoo News.
