Schoolgirl Isabelle Guyler was found dead at her family home after committing suicide but police have confirmed they have found "no evidence" she was bullied.
In a statement released on Monday, Nottinghamshire Police said they do not believe bullying contributed to the 12-year-old's death. Guyler, a pupil at Nottingham Emmanuel School, hanged herself in her bedroom on Friday.
Her suicide has prompted friends to claim she was being bullied, with one saying: "I promise they will not be getting away with this. It was all over jealousy and because you're way prettier than them."
But both police and Guyler's family have refuted the accusations as "unfounded allegations".
Detective Inspector Neil Fountain said the force was "aware" of speculation the schoolgirl had been subjected to bullying and that this had been a factor in her death.
“The investigation has included a thorough review of comments posted on social networking websites and taken statements from friends and relatives of the girl, and I would like to make it clear we have found no evidence of bullying," he added.
One relative posted on a Facebook tribute site, which has already attracted more than 1,500 members, saying Guyler had "too much confidence in herself to succumb to the cruel schoolyard taunts of jealous, competitive girls".
Carol Fearria, head of Guyler's school, said everyone was "deeply shocked" at the schoolgirl's death.
Police are currently preparing files for the coroner.
