Paranormal investigators have recorded chilling ghostly voices saying "let me out" at an infamous haunted former church.

Eerie voices, hammering sounds and unexplained "orb" lights were caught on camera as temperatures plunged to -8C at Cold Christmas Church near Ware, Herts.

Cambridge Ghost Hunters took the video at the Grade II-listed ruins, which have been a hotspot of ghost sightings for decades.
