The Wake County Sheriff’s Office arrested a ride operator after a ride injured five people Thursday.

Timothy Dwayne Tutterrow, 46, of Quitman, Ga., was booked in the Wake County jail on three counts of assault with a deadly weapon inflicting serious bodily injury. Tutterrow was working as one of the operators of a ride called the Vortex, which reportedly started moving while people were trying to board Thursday night. The ride has two arms that twirl and suspend riders. Without restraints in place, the riders fell from their seats, witnesses told The News & Observer.

An ambulance was on scene within a minute of the initial emergency call and all of the injured people were transported offsite to WakeMed Hospital within 20 minutes.

Five people were injured and three people remain hospitalized. They were identified Saturday as Anthony Gorham, 29, Kisha Gorham, 39, and a 14-year-old whose identity was not disclosed. Authorities had no further information Saturday night about the conditions of those hospitalized. Four of those injured are from the same family, fair officials said. The fifth has only been identified as an employee who had the job of securing the riders into their seats.

According to a press release from the State Department of Agriculture, which runs the fair, this is the first time this Vortex ride has been at the N.C. State Fair. There is a second Vortex ride that has been on site for several years, but it is a completely different style of ride, the press release stated.

“This is a situation that we never want to have at the fairgrounds. Any ride accident is tragic and our thoughts and prayers are with the families,” Agriculture Commissioner Steve Troxler said in a press release. “Safety is something that we take very seriously and so this accident has shaken us all deeply.”

Tutterrow’s bail was set at $225,000, and he will have a court appearance Monday in Wake District Court, reported The N&O.
