A mixed martial arts fighter received an offer of £370,000 to take on a chimpanzee, with warnings about catastrophic injuries.

Cole Johnson said what began as a joke turned into an actual bout.

The event looked to have been called off after its website was taken down over trust and safety.

It was subsequently labelled as a crypto hoax.

Separately, nine chimpanzees on Ngamba Island chose a baited box on 73 percent of trials when a human pointed, called names and made food grunts.

Pointing alone did not produce the same result.
