Watch 'Most Haunted': Accrington Police Station & Courts, Lancashire - Part 2 - Full Episode

The premiere marks the final night of Halloweek, a weeklong event bringing fans  new episodes on the show's official YouTube channel every night for a week over Halloween.

The episode ended with Yvette in hysterics after she fell over in court room number one, leaving the show's skeptic Glen Hunt momentarily concerned for her wellbeing.

Despite being exhausted after all of the activity they'd experienced so far, the team needed to push on. This time around Yvette took Karl Beattie to the lobby, where she reported feeling unwell. She told Karl "I'm really cold and I'm really shaky, and I feel sick." As they worked their way into the offices and support rooms on the ground floor, Yvette started becoming increasingly spooked by unexplained sounds around them.

Glen took resident demonologist Fred Batt, Stuart Torevell, and camera man Gregg Smith to the lower floors where they started their vigil in a series of rooms used as offices up until the building's closure, but one room was originally used as a mortuary.

After a while they split up. Glen and Gregg went to court room one to check on Glen's laptop that he'd left recording EVPs. Upon reviewing the recording they heard a strange and very clear sound that they couldn't explain.

Meanwhile, Stuart and Fred went to the cells where they heard lots of strange sounds around them and heard banging coming from a distance. They later moved climbed the stairs to court room two. Fred said he could hear footsteps behind him following him up the stairs.
