A 10-year-old girl hanged herself after a video was shared on social media of her fighting an alleged bully.

Ashawnty Davis was a victim of "bullycide," when someone kills themselves because of bullying, her parents said.

"It's just devastating," her father, Anthony Davis, told Fox31 Denver. "She was just a child of joy and she brought joy to everyone."

Ashawnty, a fifth-grade student at Sunrise Elementary school in Aurora, Colorado, was filmed after she got into a fight with another girl.

Her mother, Latoshia Harris, claimed the girl had been bullying her.

“I saw my daughter was scared,” Ms Harris said.

Footage of the fight was then uploaded and shared on the app Musical.ly.

"My daughter came home two weeks later and hanged herself in the closet," Ms Harris said.

Ashawnty died after spending nearly two weeks on life support in hospital.

Her parents hope her story will help save the lives of other young people.

"We have to stop it and we have to stop it within our kids," Mr Davis said.

"I want other parents to know that it’s happening," Ms Harris added. "That was my baby and I love my baby and I just want mothers to listen."
