According to the backinfo I got, the incident happened in Nairobi, Kenya. The video shows a couple of men climbing a building apparently in order to scare away a monkey who’s sitting on top of the roof. Turns out, it’s the monkey who scares one of the men and as a result, he falls.
You can see from the first 3 seconds of the video, that the fence made from those corrugated galvanized steel panels, that are usually used on roofs, are intact. I’m not sure what the proper name for those panels is.
Then after the man falls (at 0.20 onward), the panels are bent, which suggests he fell right on them. And even though edges on those things are not razor sharp, they are still thin so falling on them from some height is sure to leave you with gashes on the body.
I don’t have the aftermath of the incident, but I’m guessing the fallen man ended up diced up quite good. The result – one man with possible lifetime injuries, but monkey still on the roof.
