An eleven-year-old girl has allegedly been hung from a tree by a skipping rope by schoolyard bullies.

Children at Queen of Apostles Catholic School in Riverton, Western Australia, allegedly strung Amber Yoon up by her neck, causing her to choke, 9 News reported.

The poor girl, who has a heart defect, was struggling to breathe and only escaped when a horrified teacher saw what was happening and cut her down, her family say.

Amber's mother, Belinda Yoon, said her daughter's toes were barely scraping the ground and that she could have died.

WA Police are now investigating.

'We have been having issues with Amber being bullied, causing major issues with anxiety,' Ms Yoon said.

'Amber has been through more in her life, suffered more pain, and been in situations so terrifying most kids thankfully will never experience.'

The school, which claims to offer children a 'nurturing, inclusive and safe environment' and has the motto 'love, unity and peace' said in a statement that it 'continues to consult with the families impacted'.

No one has been arrested or charged.

Daily Mail Australia has contacted the school for comment.
