The boy, 6, was airlifted to hospital after reportedly falling from the Twister ride.
He was purportedly left hanging from a carriage at the theme park in North Yorkshire as his horrified mum screamed beside him.
Reports have since emerged Gemma Savage, 20, died when two cars collided on the same ride, then called Treetop Twister, 18 years ago.
A witness from today’s incident said: “Me and my eldest daughter were in the queue for the Twister ride, which is like a rollercoaster but with individual spinning carriages.
“We were about ten minutes from the front of the queue when we saw the little lad hanging out of the back of his carriage.
“His head was well behind the back of it and he was out of his restraints. He was in the carriage with his mum, who was screaming hysterically”
“His head was well behind the back of it and he was out of his restraints. He was in the carriage with his mum, who was screaming hysterically.
“Everyone in the queue was shouting for the ride operator to stop the ride for about ten to 15 seconds but they didn’t seem to have noticed.
“Then the boy must have fallen about 15ft. We jumped over the barrier to try and help and one man identified himself as an off duty police officer and he sort of took over.”
