A young footballer has been remembered as a "sweet and caring" friend who died while on a trip to a water park.
Pals paid tribute to classmate Kyra Hill, 11, after she died when she reportedly got into trouble at an inflatable assault course at the Liquid Leisure Windsor in Datchet, Berkshire.
Her death is being treated as unexplained but not suspicious, Thames Valley Police said.
The alarm was raised when she did not return as parents and staff launched a desperate search to find her.
She was reported missing at roughly 3.55pm and was found just after 5.10pm before being rushed to Wexham Park Hospital where she died.
Kyra was said to be a keen footballer and was a big Manchester United supporter.
She played for Coombe Wood School in Croydon.
One 12-year-old, who played football with the schoolgirl, told Mail Online : "Kyra was so kind. She was really smart, she was at the top of all our classes.
"She liked to make people smile, she cared about people."
A mum of one of her classmates said: "She was such a sweet girl."
Liquid Leisure said the aqua assault course will remain closed for the rest of the week “out of respect” for her family.
A 41-year-old woman from South Buckinghamshire, who did not want to be named, was at the "busy" water park with her teenage daughter on Saturday, having been several times before.
The woman said the situation was "an absolute tragedy" for the family and friends of the girl while she and others at the park felt "shock" and "helplessness" at the scene.
The woman added that her daughter had attended a safety briefing beforehand and said she was told not to push in people they did not know.
She was also told not to use abusive language and that a whistle would be blown 10 minutes before the end and a second whistle would be blown when the session was finished, the woman said.
The 41-year-old added that she began to feel "uneasy" about the ratio of lifeguards to visitors.
However, she said: "I reasoned with myself that my daughter and friend had their life jackets on and the session would soon be over."
Soon afterwards a lifeguard began to shout, telling them to get off the inflatable course, she said.
The woman continued: "We then realised a child was missing as two frantic women ran past screaming the child's name.
"There seems to be no plan of action with the LL staff. A few lifeguards jumped into the water and started searching in what appeared to be a very non-methodical way.
"Another member of staff started asking other members of staff if they were lifeguard trained. No one appeared to be in charge and there was no coordination in managing the situation.
"For the adults and children left on the riverside we didn't know what to do, there was no communication and no evacuation procedure.
"There is one small entrance and exit at LL and the emergency services arrived quickly and in huge numbers, they couldn't have done more."
In an update on Tuesday, Thames Valley Police said the incident is not being treated as suspicious and a file is being prepared for the coroner.
The force said that officers are working with the Royal Borough of Windsor & Maidenhead council as they conduct an investigation over whether there were any health and safety breaches.
The victim’s next of kin continue to be offered support by officers.
Meanwhile, a public inquiry into the matter is to begin on November 8.
A Liquid Leisure statement said: "Our thoughts and prayers are with the family, friends and all those affected by this desperately tragic and upsetting incident.
"As Thames Valley Police are in the early stages of the investigation, it would not be right for us to add a further comment, but we will continue to fully support and assist them throughout the process."

Its website says: "Liquid Leisure is home to Europe's Largest Aqua Park and the first official Ninja Warrior UK Aqua Park, set on one of the most beautiful private freshwater lakes amongst stunning parkland in the heart of Berkshire."
Flowers and messages were seen outside Liquid Leisure’s closed gates on Tuesday as tributes poured in following the girl’s death.
