Lions maul alleged rhino poachers to death in South Africa Authorities found the "hallmarks of a gang intent on killing rhino."

Several animal poachers became the prey themselves after being mauled to death by lions as they allegedly trespassed in South Africa’s Sibuya Game Reserve, the reserve owner said.

The Eastern Cape reserve is a camping and safari site for tourists.

The handler was unconcerned because it is not unusual for the lions to make noise, Fox added. But the reserve's anti-poaching unit later noticed human remains near the lions Tuesday.

“I was immediately called to the scene where, along with the Anti-Poaching Unit, we found the high-powered rifle, gloves, wire cutters and the remains of a backpack with food, water and other supplies,” Fox said Thursday. “All the hallmarks of a gang intent on killing rhino and removing their horns.”

Authorities are now investigating the incident, which is believed to have involved two or three alleged poachers who walked into a group of six lions, Fox said.

Rhinoceros poaching is up by more than 8,000 percent across South Africa since 2007, a 2017 ABC News report found. Poachers can sell the horns for as much as $300,000 each on the illegal wildlife markets in Asia, where people believe they have medicinal value.
