It is emergency calls that firemen are expected to answer, not embarrassing ones.
But thanks to the popularity of the erotic novel Fifty Shades of Grey, they are increasingly being called out to free people handcuffed to beds.
London Fire Brigade said it had turned out to 79 such incidents – and nine instances of men with rings stuck on their penises – and urged people ‘always keep the keys handy’.
Third officer Dave Brown, said: ‘Some of the incidents our firefighters are called out to could be prevented with a little common sense.
‘I don’t know whether it’s the Fifty Shades effect, but the number of incidents involving items like handcuffs seems to have gone up.
‘I’m sure most people will be fifty shades of red by the time our crews arrive to free them.’
