Yvette Fielding and the Most Haunted team are no strangers to the imposing police station and courts in Accrington, but in this previously unseen episode filmed at the vast abandoned building in Lancashire, we finally get to see what happened to the team on their first ever investigation there. The team's mammoth investigation is split into two parts with the conclusion premiering tomorrow night as part of Most Haunted's Halloweek, a weeklong event bringing fans  new episodes every night over Halloween.
