CSI: Luton is the first of the popular series of detective dramas, CSI to be set in the town of Luton, England, UK indeed it is only the second series to be based outside the United States. It was originally intended that this series be based around the better known city of London however, owing to the sheer amount of serious crime that took place in the town Luton was chosen instead. The program deals in a very realistic manor with much of this criminal activity including the vandalisation of street furniture (lamp-posts, pillar-boxes, benches, etc.), playing of ball games in areas where signs command that ball games not be played, teenagers writing their names in wet concrete and perhaps most controversially of all – numerous incidents of bicycle theft by multiple men named Nathan.
