Alton Towers Smiler shut after wheels hit four on ride.
A new £18m roller coaster at Alton Towers has closed after wheels fell off and hit four people in the front carriage.
A spokeswoman said some "small guide wheels" came off The Smiler as it was being pulled up an incline.
Kevin Hayes-Heath, who was in the carriage with his partner Wayne, said the incident was "pretty frightening".
Debris hit him on the shoulder and his partner in the face. A teenage girl and her father were also hit, he said.
"You are at the highest point of the ride and you've got all these loops to do and you just think that the carriage is going to come off," Mr Hayes-Heath said.
"We were shouting at them to stop the ride because they were about to send another party off."
