This episode was shot as a two-part story featuring the return of Diane Noble (
Kaye Wragg), newly promoted to sergeant. However, when ITV announced changes to the show's format in January 2009, including a reduction in the number of episodes shown per week from two to one, the size of the cast had to be reduced and the producers decided that they could no longer proceed with the storylines planned for Diane Noble. Hence, this story was heavily edited to fit in one episode, and new scenes were shot explaining that Diane was transferring to Barton Street station.
