A two-year-old boy has died after a bouncy castle was lifted off the ground by a strong gust of wind, US authorities have said.

The parents of the boy - named in reports as Bodhi Naaf - are "grappling with unimaginable grief" following the incident on Saturday, a GoFundMe page said. The "tragic accident" happened near Casa Grande, Arizona, according to a statement from the Pinal County Sheriff's Office.

"Several children were playing in a bounce house when a strong gust of wind sent it airborne into the neighbouring lot," the sheriff's office said. "A two-year-old child was transported to the hospital where he passed away." A second child was taken to hospital with injuries that were not considered life-threatening, Sky's US partner NBC reported.

A GoFundMe page has been set up for Bodhi's parents Karl and Cristy, who are expecting a child in late May. "This devastating loss has left Karl and Cristy grappling with unimaginable grief," it said.

"Adding to their challenges, Cristy is due to give birth to their second child on 31 May 2024. Amidst their sorrow, they face the daunting task of preparing for the arrival of their newborn.

"As a community, we want to offer our support and alleviate the financial burden that accompanies such tragedies." The fundraising page has received more than $138,000 (£110,000).
