A huge manhunt has been scrambled in Germany after a teenager stabbed a nine-year-old boy to death and posted a video of the murder on the internet.
Police were called on Monday after the child's body was found in the cellar of a home in Herne, North Rhine-Westphalia.
The killer has been named as Marcel H, a martial arts enthusiast, who reportedly filmed the murder and uploaded it onto the dark web.
An dark web user, who claimed to know the killer, contacted police to tell them: "I have just seen a boy murdered on the internet."
