Girl, 7, dies while playing on a bouncy castle

(FOX NEWS) - Two people were arrested on suspicion of manslaughter after a 7-year-old girl in Britain died Saturday when the bouncy castle she was playing in was swept away by a strong gust of wind, Sky News reported.

The inflatable attraction flew over trailers in a park and landed at the bottom of a hill.

Summer Grant, from Norwich, was treated at the scene around 4 p.m. and taken by air to a hospital, but she was unable to be saved.

"It was a freak gust of wind that caught everyone unawares," said Ray Smith, a representative of the Showman's Guild of Great Britain. "It actually pulled the safety stakes out of the ground."

A 27-year-old man and 24-year-old woman from the firm that runs the bouncy castle attraction were arrested on suspicion of manslaughter by gross negligence. Neither has been identified.

"Everyone here is absolutely devastated, in fact, everyone in the fairground industry is shattered by this," Smith told Sky News. "It's so appalling that this little girl came to have a lovely day out with her family and lost her life."

Smith said if the winds had been consistently that high, the castle and other inflatables would have been closed.

Families had gathered at Harlow Town Park in Essex for an Easter event.

Essex police were working with the Health and Safety Executive in their investigation into the incident. Police said they were aware of video footage of the incident and were working to obtain it.

Saturday's tragedy was the second bouncy castle mishap at Harlow Town Park. Last year, three children required medical attention after a bouncy castle collapsed at the park.
