A group of poachers were bested by a pride of lions after they broke into a South African game reserve in a bid to stalk and slaughter a herd of rhinos.

At least three men made their way onto the Sibuya Game Reserve in the early hours of the morning on Monday. They were โ€œarmed with, amongst other things, a high powered rifle with a silencer, an ax, wire cutters and had food supplies for a number of days,โ€ according to a news release.

Reserve owner Nick Fox said they had โ€œall the hallmarks of a gang intent on killing rhino and removing their horns.โ€

An anti-poaching dog alerted its handler around 4:30 a.m. on Monday, but the handler brushed off concerns. At the same time heโ€™d heard a commotion coming from the lions so he suspected thatโ€™s what prompted a reaction from the dog.

โ€œHowever, it now appears likely that the dog had been alerted by something else out of the ordinary coming from the lions,โ€ Fox said.

Field guides on a game drive on Tuesday evening reported that theyโ€™d discovered human remains as well as other items โ€œin the immediate vicinity of the lions.โ€

When he arrive on the scene, Fox said they discovered the high powered rifle, gloves, wire cutters and the remains of a backpack with food and water.

โ€œClearly the poachers had walked into a pride of six lions and some, if not all had been killed,โ€ Fox said.

Investigators were unable to examine the scene for evidence on Tuesday night and were forced to wait for daylight. Fox said heโ€™s arranged for the reserve vet to โ€œdart the entire pride of lionsโ€ so police, forensics teams and the anti-poaching unit may search the area for clues.

Itโ€™s unclear how many people were killed on the reserve at this time.
