The man was found by a relative with ‘serious injuries’ at a property in the sparsely populated southern town of Redmond in Western Australia. He is thought to have been keeping the wild animal as a pet.

A wild kangaroo is suspected of killing a 77-year-old man who was keeping it as a pet, Australian police said on Tuesday, in what was reportedly the first fatal attack by one of the animals for 86 years.

The man, who has not been identified, was found by a relative on Sunday afternoon with “serious injuries” at a property in the sparsely populated southern town of Redmond in Western Australia, police said.

“It is believed the man had been attacked by the kangaroo earlier in the day,” a state police spokesman said. An ambulance crew raced to the scene, but the man died there.

“At the property there was a kangaroo that was preventing the ambulance crew from accessing the injured man,” the police spokesman said.

Police said they had to shoot and kill the animal, as it “was posing an ongoing threat to emergency responders”.

The kangaroo was believed to be a wild animal being kept by the man as a pet, police said.

Though the kangaroo species was not identified, the Great Southern region of Western Australia is home to the western grey.

The male western grey can grow up to 2.2 metres (more than seven feet) long and weigh up to 70kg (154 pounds).

Australian media said the last reported fatal attack by a kangaroo was believed to be in 1936.

In that incident, The Sydney Morning Herald reported that a 38-year-old man, William Cruickshank, had died in hospital in New South Wales, months after being attacked as he tried to rescue two dogs from a large kangaroo. The attack left him with a broken jaw and extensive head injuries.
