This is the shocking moment a children's rollercoaster slides of its tracks and injures three children sent crashing to the ground.
The Pinfari Wacky Worm ride at a theme park in Cianorte, Brazil - known by locals as the "Minhocão" ride - derailed while dozens of people were onboard on Wednesday evening.
Onlookers watched in horror as young children were sent crashing to the ground in terrifying scenes.
In a video taken by a witness, the ride begins at a slow pace as it travels along the tracks.
As a bend approaches, the ride makes a sharp turn but derails and topples ove, sending riders falling off their seats.
Three people were injured in the ordeal and treated at a local hospital.
The ride underwent three safety inspections, according to local reports.
Officials are now investigating the incident.
In July, three people were killed and 27 were injured after a ride snapped mid-air at a theme park in India.
The incident happened on board the "Discovery" ride at Kankaria Amusement Park in the city of Ahmedabad, Gujurat in India.
The shocking video shows the ride swinging back and forth on its pendulum before it dismantles, sending riders crashing several feet down to the ground.
Shocking images show victims covered in blood while others were still trapped in their seats.
