VIDEO: Estate agents tricked into thinking house is haunted

Hidden cameras, rigged rooms, and a sweet old lady.

A classic hidden camera prank needs to catch its victims with their guard down - so who better to scare in a haunted house than those who spend all day walking around strangers' homes?

Several estate agents came to view this home - which had been rigged by professionals to be "haunted" - and met a sweet old Rosie at the door. "It wasn't my house - it was my brother's, who sadly passed away in this house," she told them.

Stick with the clip until 2:30 when the chair gets involved and the screams start. It's brilliantly rigged.

The set-up is a promo piece for Sky Living's upcoming three-part drama "The Enfield Haunting", which covers the story of Britain's most famous poltergeist from the 1970s.
