Floating on a river boat near a Liberian island, vet Richard Ssuna watches intently as animal carers wade towards the shore hurling fruits and imitating chimpanzee calls as they go.

The beach is empty, but the sound of rustling and chimpish grunts begins to fill the green undergrowth. Slowly, an ape knucklewalks out onto the beach to grab some food.

THIS is the secret African island inhabited by super aggressive "monster'" chimps all freed from a US testing laboratory, writes the Sun.

The apes -who are infected with contagious diseases- were abandoned on the Liberian river island after being released by their captors.
