There has been an unprecedented rise in a number of cases for people trapped in handcuffs, The London Fire Brigade said blaming it on a best-selling erotic novel's "Fifty Shades of Grey's" effect.

"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," Third Officer, Dave Brown, said in a press release. "I'm sure most people will be Fifty Shades of red by the time our crews arrive to free them," he said adding hat the nuances cost taxpayers £377,000 (nearly $580,000).

"I'm sure most people will be fifty shades of red by the time our crews arrive to free them," the officer said on the lighter side.

Since 2010, authorities have responded to more than 1,300 incidents of people getting stuck in everyday household items.

In the past three years the fire service has rescued 79 people unable to escape handcuffs. There have been several calls from men with rings stuck on their private parts and one odd case also included a man where his manhood was trapped in a toaster and another in a vacuum cleaner.

So what's the advice that the department would like to issue? "Our advice is simple," a spokesperson said. "If the ring doesn't fit, don't force it on."

A growing number of London residents have reported getting stuck in handcuffs and toilets in the last three years, according to the report published. The department has urged those using handcuffs in the bedroom to "always keep the keys handy."

British author EL James's novel based on sado-masochistic theme "Fifty Shades of Grey" has sold more than 70 million copies since 2011 with book rights having been sold in 37 countries and set the record as the fastest-selling paperback of all time, surpassing the Harry Potter series.

The London fire fighters have responded to 1,300 cases of people trapped or stuck -- more than one per day in last three years. According to their data there were 18 children with their heads stuck in potties or toilet seats, five people with their hands trapped in shredders, and four with hands stuck in blenders.
