A 12-year-old boy hanged himself after playground bullies terrorised him for the way he talked, it is believed.
Bradley Wiseman, who is believed to have been targeted because of his well-spoken voice, was found at his home on Monday.
Neighbours have rallied round to help the boy's 37-year-old mother.
One neighbour said: 'We're all here for her. He was a lovely lad, so polite. It is completely out of character – he never would have done it if he wasn't being bullied at school.
They bullied him because he talked politely, he was very well spoken. You wouldn't have known he came from round here.
'He was a lovely kid and it is so sad what has happened. We are all devastated.'
An online memorial page on Facebook has already had hundreds of comments.
Shelly-Louise Hindley wrote: 'Hope their guilt follows them always and they realise the severity of what they have caused. . . Rip bradly lovee.'
Anthony Rushton added: 'You don't deserve this, no one does. Its an awful shock to everyone, we have all been hurt by this.'
Rugby-mad Bradley attended Sir Thomas Wharton Community College and played for Doncaster Rugby Union Football Club's Under-12s.
His coach John Wills said: 'He was a lot of fun. There was no evidence of him being bullied at rugby practice or during games. Bradley was really popular with all the other boys.'
Mary McCorry, headteacher at Sir Thomas Wharton Community College, said: 'Bradley had settled into school well and there have been no reports of bullying or any problems that we are aware of.
'On behalf of everyone at Sir Thomas Wharton, we are deeply saddened to hear of the sudden death of one of our pupils.
'Bradley was a bright and popular boy and will be very much missed at school.'
An investigation by South Yorkshire Police has been started following the discovery at 4.30pm on Monday.
A spokesman said officers were not treating the death as suspicious.
