This made me laugh when seeing it on the BBC Website.
It appears that in New Zealand they cannot, by law, show photos of young criminals in order to name and shame them. But in this case, the criminal has been described as a 16 year old who looks like Robbie Coltrane.
I have to say that whenever I see someone doing anything suspicious I always ask myself "who does the person look like ?" so that I can store a mental image, so this probably isn't as daft as it sounds.
