Who'd have thought an 11-year-old child dressing as a control freak BDSM fanatic would cause such an uproar?

Certainly not Liam Scholes from Sale, Manchester, who showed up to his school's World Book Day celebrations dressed as Christian Grey from 50 Shades Of Grey.

He donned a shiny grey suit and bowled up to Sale High School carrying an eye mask and some cable ties Thursday expecting some laughs, but was told by teachers the costume was inappropriate.

His mother Nicola received a phone call from the school saying he wouldn't be able to participate in the class events or even feature in a group photograph.

“Me and the teacher agreed to disagree and it’s not being taken any further," she told Manchester Evening News, "but I was disappointed for Liam that he’d been stopped from taking part and that he’s had a dressing down."

“One of the teachers went dressed as Dexter and I don’t see why sex is seen as more offensive than murder," she added.

World Book Day also caused controversy Thursday when dozens of children dressed up as Elsa from Frozen, which quite notably isn't a book.
