The fair said in a news release Saturday that 46-year-old Timothy Dwayne Tutterrow, of Quitman, Ga., had been arrested. Witnesses say the ride had stopped and people were getting off when it started moving again.
Wake County Sheriff Donnie Harrison said after inspecting the ride, investigators determined it had been tampered with and critical safety devices were compromised.
Tutterrow is employed by an independent ride contractor. A telephone call to Tutterrow was not immediately returned.
Three people are still in the hospital.
