In the dead of night, one office block in the U.K. lay silent and still. But as security staff looked on, what they saw on CCTV cameras terrified them. A chair shot across the floor, and then before they knew it, the whole building was rattling with apparent paranormal activity.
Castlefield House is an office block seemingly like any other. The nondescript workplace sits on Liverpool Road in the northern English city of Manchester, and during the day people fill the space, working at their desks.
However, each night, the block lies deserted. The only people remaining in the office are the security guards who monitor the corridors and workspaces overnight. Most of the time, their job is uneventful; yet one night in 2012 proved to be anything but.
