At least 20 fairground ride goers were injured when a chair swing carousel collapsed while it was packed with children.
Officials say at least 10 children were hurt when the ride toppled over in full flight at a festival in Palma Campania, near Naples, Italy, on July 10.
One 12-year-old girl remains in hospital in Naples, report local media.
Phone video footage of the drama shows the chair swing in operation before its base starts to wobble uncontrollably.
As the ride starts to lift, spectators begin to flee and the chair swing topples over onto its side, scattering its passengers.
Local police are investigating the accident at the Madonna delle Grazie (Our Lady of Graces) festival.
They have seized the fairground ride and investigators currently believe structural failure may be to blame.
They are investigating the person responsible for the fairground - a woman from nearby Poggiomarino - for causing injury through negligence.
They have seized papers from her detailing the fairground's insurance policy and the carousel's last technical test.
Palma Campania mayor Nello Donnarumma reported that the incident took place just hours before the fairground was due to be dismantled.
Investigations are ongoing.
