Potter star used to crack crime :

A wanted poster featuring Robbie Coltrane is being used by police in New Zealand to try to catch a teenage burglar who resembles the actor.
Detectives stressed the Cracker and Harry Potter star is not suspected of any crimes, but said the thief looks like a 16-year-old version of him.
The poster has been distributed to homes in the Christchurch area of the South Island.
New Zealand law bans the publication of pictures of juvenile criminals.
Below the heading 'Wanted' is the picture of Coltrane, underneath which are the words 'Active burglar in this neighbourhood'.
