A 13-year-old boy killed himself after being routinely forced to practise his own suicide every day by school bullies, it has been claimed.
The teenager leapt to his death from an apartment building in Otsu, central Japan, which has one of the world's highest suicide rates.
His death has prompted a series of bomb threats against the school and local government over claims they didn't do enough to stop the taunts.
There are also reports that his teacher apparently brushed off the abuse as a joke.
A letter sent to the boy's school this week threatened that the building would be bombed unless the pupils and teachers involved apologise, local authorities said.
A local police officer said: 'The school called police Monday after receiving a threat in the mail, which demanded pupils and teachers involved in the bullying publicly apologise'.
Other threats included bombing regional government buildings, a local education board and even the police department, but it was unclear if one person was behind all the threats, they said.
A survey of 15 pupils at the school revealed that the boy was routinely subjected to a litany of abuse by bullies - but still nothing was done. It also revealed that his teacher was aware of problems but ignored them.
They described how the victim, who has not been named, was beaten in a bathroom, forced to practise taking his own life, and told to put a dead sparrow in his mouth.
He was also forced to shoplift for the bullies and extorted money from 'friends' and there were reports he was repeatedly held in a headlock and beaten, had his pants pulled down, and forced to eat dead bees.
The boy's parents are trying to sue three students, their parents and the Otsu Municipal Government, seeking damages of 77.2 million yen - approximately $966,235 - following his death in October last year.
The school has disputed any link between the allegedly abusive pupils and the boy's death while the local government admitted the boy had been bullied, but argued it could not be proved that the suicide was the result of the bullying.
The boy was found dead on October 11, close to his home. He did not leave a suicide note. Police said at the time the cause of his death was suicide.
Barely teenagers and the evilness inside these kids is just despicable.
I bet the parents of these children are the types to let them do whatever they want and may even be afraid of them. Or maybe they're bullied at home themselves. Regardless, I hope these kids get what's coming to them. There are no excuses for the atrocious things they bullied this kid into. I hope they get their asses rammed by bigger kids one day.
This is every parent's worst nightmare, that their child is being bullied and worse.
It is also a sad thing that the child did not feel comfortable reaching out to his parents or school counselors. Every child has something to say, even if it takes a while. Adults need to show more care and empathy and these types of things would not have to reach that point. The parents of those bullies probably lost touch with their own children a long time ago.
