Fifty Shades Of Grey: Boy aged 11 banned from school's World Book Day for BDSM lover Christian Grey outfit

An 11-year-old boy was barred from his school's World Book Day after turning up in a costume inspired by S&M best-seller Fifty Shades Of Grey.

Teachers were shocked when Liam Scholes from Manchester arrived for lessons at Sale High School in a grey suit, carrying cable ties and an eye mask. The school had asked Year 7 pupils to dress up as famous literary characters as part of the World Book Day celebrations.

He was subsequently banned from posing for class photographs and told he could not participate in activities as his costume, inspired by the erotic series, was "offensive".

Liam's mother Nicola Scholes, a primary school teacher, defended her decision to send her son to son dressed as character who has a passion for bondage.

"One of the teachers went dressed as Dexter and I don't see why sex is seen as more offensive than murder, "she told Manchester Evening News.

"If it was a primary school I could understand but it's a secondary school and the book and the film have been everywhere – it's one of the most famous books in recent years and it's not like the pupils will be unaware of it."

Scholes argued the intriguing businessman is one of the most-talked about characters in recent times. And despite the backlash, she has no regrets.

"At first we laughed it off but then we discussed it with a few friends and saw the funny side and decided it was quite a good costume idea," she explained.

"He went in a suit and shoes and with an eye mask and cable ties. The cable ties were tiny and not enough to do anything with them. We didn't think there would be a problem."

The Fifty Shades Of Grey movie, released in February, stars Dakota Johnson as submissive Anastasia Steele and Jamie Dornan as her bondage-obsessed playboy billionaire, Christian Grey.
