UK- A teenage schoolboy was pulled around his classroom on a lead and spanked by a stripper after a birthday surprise blunder.

The pupil’s mum had ordered an agency to give her son a “surprise” on his 16th birthday – and the teacher had even agreed to film the prank.

But it all went wrong when the unnamed company sent a stripper dressed as a policewoman instead of a “gorillagram” – in what it called a booking error.

One witness told reporters: “She asked the lad to stand up, which he did, and told him he had been a very naughty boy because he hadn’t been doing his homework.

“Then she put on some Britney Spears music and got out a collar and lead from her bag and told him to put them on.”

After walking the boy round the classroom and spanking him with a whip – the action turned even more blue.

“She took off some clothes until she was down to her bra and pants, pulled out some cream, put it on her buttocks and told him to rub it in,” the source said.

It was at that point the shocked teacher – who had not been told what the surprise was – called an end to the show.

A spokeswoman for the local education authority, Nottinghamshire County Council, said they were investigating how the incident happened.

She confirmed nobody had been suspended from Nottingham’s Arnold Hill School and Technology College and the police were not involved.

The spokeswoman said: “We and the school are investigating into the situation.”
