See the unexpected guest that joined a safari tour bus in Tanzania.

A cheetah sneaked into a safari vehicle in the Serengeti National Park in Tanzania.

According to reports, the family tour group were told to stay calm and silent whilst the cheetah climbed into the back seat, sniffed around and explored the jeep.

Fortunately, the curious cat's visit was very brief, and he left leaving no one hurt.

The images were obtained from video footage by Peter Heistein, a landscape and wildlife photographer.
