'Fifty Shades of Grey'
London Fire Brigade has revealed some of its most embarrassing call-outs.
The service has dealt with 393 sex-related incidents since April involving people being trapped in handcuffs and other devices - and says it expects to see the number increase markedly after the release of the 'Fifty Shades of Grey' film.
London Fire Brigade tweeted: "A woman rang after her husband was locked in a titanium chastity belt. Keep those keys handy! #fiftyshadesofred"
'Fifty Shades of Grey' stars Jamie Dornan and Dakota Johnson and is released in the UK on Valentine's Day (14.02.15).
