Tristan is on patrol with Bella – and is called to an incident of criminal damage, in which young man has smashed the window of a young offenders’ rehab centre. Having found the youth concerned, Tristan discovers that the situation is far more serious as the lad has a piece of broken glass in one hand, and knife in the other – and he’s been slicing at himself with the glass. The youth refuses to be placated, and threatens to keep on cutting at himself, before taking exception at the presence of the camera and running at the cameraman.
