'New' giant ape found in DR Congo

Scientists believe they have discovered a new group of giant apes in the jungles of central Africa. The animals, with characteristics of both gorillas and chimpanzees, have been sighted in the north of the Democratic Republic of Congo. According to local villagers, the apes are ferocious, and even capable of killing lions.
I must admit, when I originally read this story, I thought it must be nonsense: the discovery of a previously unknown great ape sounded totally implausible. But I later read the story in more depth in New Scientist, and it might not be as far-fetched as I believed. There is certainly intriguing evidence that there might be a new species of giant ape in the Congo, although some scientists believe it to be an already-known sub-species of chimpanzee, while others think it could be a gorilla-chimpanzee hybrid (which, in itself, would be remarkable).
