A FRANTIC dad screamed “my daughter is in that” as he chased a bouncy castle that blew away, killing his seven-year-old daughter inside, a court heard.

Summer Grant died from multiple injuries after the inflatable attraction flew across a park in Harlow, Essex, The Sun reports.

The attraction was blown 300 metres down a hill and smashed into a tree with the youngster inside before finally coming to a rest.

Her dad Lee Grant heard Summer scream and chased the bouncy castle as it started “cartwheeling” in the air, Chelmsford Crown Court was told.

The frantic dad had tried to pull it to the ground as it blew through the air at Thurstons Fun Fair on Easter Saturday as Storm Katie barrelled in.

But the court heard it was moving too fast for Lee to catch it and Summer tragically died from her injuries after being rushed to hospital.

Fairground worker William Thurston, 29, and his wife, Shelby Thurston, 26, both deny manslaughter by gross negligence and a health and safety offence.

Tracy Ayling QC, prosecuting, said: “[Lee] turned and saw that the dome inflatable had lifted into the air, appeared to hit a caravan before flipping over.

“He said ‘My daughter’s in there’.”

Ms Ayling said William Thurston was among those who chased the bouncy castle as it blew away and, when he went to help Summer, it appeared “she was very badly injured and struggling to breathe”.

The prosecutor continued: “It’s the Crown’s case that they breached the duty of care they owed to Summer Grant by failing to ensure that the bouncy castle, called a circus super dome inflatable, was adequately anchored to the ground and failed to monitor weather conditions to ensure it was safe to use.”

Health and safety guidelines state that inflatables should not be used at wind speeds over 19km/h — but winds had reached between 35 and 40km/h on the day of Summer’s death.

The couple had “planned” to take the inflatable down but decided to let Summer have a few more minutes.

Mrs Thurston told police: “Then there was a gust, like a freak tornado type wind — a massive gust that came out of nowhere.”

The court heard that the inflatable dome was attached to the ground by 15 anchor points — each of which includes a metal D ring — and the stakes came with the dome when it was purchased.

Ms Ayling spoke about the inflatable and its formal inspection.

She said: “Its most significant shortfall was an insufficient number of round anchorage points.

“This means that even when secured to the ground using all of these, the inflatable could still blow away.”

She told the court that a health and safety inspection of the dome after Summer’s death found that the marking of the exit to the dome was not right, nor was the area by which the inflating blower was meant to be attached to the dome.

Summer’s parents, who lived in Norwich, paid tribute to their daughter at the time.

Her mother, Cara Blackie, said Summer was a “bright, beautiful and most loving little girl”, and her father described her as the “most happy, polite and beautiful girl in the world”.

The trial continues.
