A legendary lion that was studied by Oxford University experts has been cruelly killed in Zimbabwe.

Blondie was shot dead by heartless trophy hunters during the week of June 29 outside Hwange National Park, the country's largest natural reserve.

The lion was reportedly fed chunks of meat from the back of a truck to bait him away from the park, where poaching is prohibited, and into a hunting area.

The tragedy came just three months after research experts fitted Blondie with a GPS collar to track him and his pride of 10 cubs and three adult females as part of a long-term study.

There are concerns that a professional hunter involved in the hunt was aware that Blondie was collared and that he had dependent cubs.
