Police have named the seven-year-old girl who died when a bouncy castle blew away at an Easter funfair.
Summer Grant, from Braeford Close in Hellesdon, died after suffering serious injuries following the tragedy.
Detectives have launched an investigation after the incident involving a bouncy castle at an Easter fair in Harlow Town Park yesterday afternoon.
She was taken to Princess Alexandra Hospital in Harlow just before 5pm but died from her injuries.
A post mortem examination was carried out today which established the cause of her death as multiple injuries.
A 24-year-old woman and a 27-year-old man, both from Cambridgeshire, have been arrested on suspicion of manslaughter by gross negligence.
The arrested man and woman have been bailed pending further enquiries to report back on May 4.
The pair are thought to be from the family-run firm that owns the bouncy castle.
The incident happened on the third day of the fair, which was due to run until Tuesday, March 29 and which was organised by Thurston fun fairs. It remains closed today.
It understood that the bouncy castle was ripped from its moorings by the winds and travelled about 150 metres.
A crowdfunding page has been set up to offer support to the girl's family. It has a target of £5,000 and has already raised almost £1,000.
A representative for the organisers said a sudden gust of wind blew the dome-shaped inflatable over a number of trailers and caravans on the site as horrified families looked on. Police said weather conditions on the day will be a factor in their investigations.
The Met Office had issued a severe weather warning for Essex yesterday, predicting strong gusts and heavy showers.
Ray Smith, a representative of the Showmans Guild of Great Britain, said: 'It was a sudden gust. Had it been a consistent wind they would have closed down all the inflatables.'
Asked about how the inflatables were set up he said: 'I know the (Thurston) family and I am very confident they had staked it out properly. Obviously there is a full investigation to be held into how this could have happened and to make sure it can never ever happen again.'
Today, tributes have been left at the gate of the park, with one card on a bunch of flowers reading: 'God has taken a beautiful girl for his angel. RIP Princess.'
An investigation into the death is being led by the Kent and Essex Serious Crime Directorate, while the Health and Safety Executive said it was assisting the police.
Detective inspector Daniel Stoten said: 'This is a very tragic incident where a young girl has lost her life. My deepest sympathies go out to her family.
The weather will certainly make up part of this investigation - whether the weather was a factor and whether or not it was appropriate for the ride to be running.
'It will be a complex and thorough investigation - I do not anticipate this to be a quick inquiry, it will be a lengthy investigation.
'We will be speaking to scientists in relation to the weight of the ride, the type of weather, the ground underfoot, the moisture content and how the ride was tethered.'
Officers are also looking for video footage of the incident which has reportedly been circulated.
Family liaison officers are supporting the girl's parents.
The East of England Ambulance Service and the Essex and Herts Air Ambulance were called at about 4.15pm to treat the girl.
Last May, a bouncy castle collapsed while children were playing on it during a funfair in the park, with reports at the time suggesting three children were treated by paramedics.
Harlow Council officers visited the site and recommended a number of health and safety improvements, including better stewarding of the event.
