The fact that an armed robbery was caught on a bicyclist's helmet camera is alarming enough, but the story doesn't end there.
This video is sweeping the Internet today because these criminals were oblivious to the fact that they were being taped.
A man named Malcolm Fox was apparently riding in the South African city of Somerset West. He's nearing the end of the ride when criminals jump into his path and rob him at gunpoint.
They steal is cell phone, car keys, sunglasses, and even his bike. But the whole time, they have no idea they were on camera.
He put the video on YouTube, contacted police, and investigators eventually tracked down three people. They were arrested.
Fox was not injured in the ordeal.
