Watch 'Most Haunted: Short' At HMP Shrewsbury Prison - Full Episode

The prison we see today has stood since 1877 and has housed both men and women up until 1922, when C-Wing was shut to female inmates and opened up to vulnerable prisoners, those who needed to be isolated from the general population in A-Wing and B-Wing.

This time around Yvette braves the back rooms on her own. A labyrinth of seemingly never ending corridors, where the prisons padded cells, mortuary, condemned cells and even the execution room are.

Meanwhile, Karl and Stuart investigated A-wing, which is said to be the most haunted part of the prison, perhaps due to its dark history of suicides resulting in sad, angry souls being trapped between this world and the next. Most of those who took their own live did so on A-wing, at one point there was one a week.

The team experienced a range of activity from knocks bangs, footsteps and even a physical attack on Stuart Torevell, who was floored after being hit in the stomach by an unseen force.
