A man and woman have been arrested on suspicion of gross negligence manslaughter after a three-year-old girl was thrown from a seaside inflatable trampoline and died.
Ava-May Littleboy died in hospital after the incident at the beach in Gorleston-on-Sea, Norfolk, on July 1.
The pair are in their 40s and from the Great Yarmouth area, Norfolk Police said.
They are awaiting questioning at Great Yarmouth Police Investigation Centre.
A post-mortem examination recorded that Ava-May died of a head injury.
Police said witnesses reported hearing a “loud bang” before the inflatable “apparently burst”.
In a tribute issued through police, Ava-May’s family said: “She was not your ordinary little girl, as anyone she met she would leave a lasting impression on.
“Anyone that met her would not want to forget her. Her infectious laugh and smile could light up even the darkest of rooms.”
The incident led to calls for the Government to consider a temporary ban on inflatables in public spaces.
Havant Borough Council has banned the use of bouncy castles or inflatables at any events on its land until the “outcome of the inquiry into the cause of the explosion of the bouncy castle is known”.
