The amazing thing is that the boy survived! This happened in November last year but the police are only now releasing the graphic image as a means to warn about knife crime.
The stabbing was the end result of a robbery at a supermarket in Southwark in London. The knife entered the kid's head just above the eye and ended up as far back as his ear.
The police have said that the releasing of the image is part of a wider campaign to crack down on knife and gun violence in London.
