OMAHA, Neb. (AP) — A Nebraska official says investigators have found no indication that a spinning carnival ride was malfunctioning when an 11-year-old girl’s hair got caught in it, ripping her scalp.

Nebraska Labor Department spokeswoman Grace Johnson also said Monday that investigators have no reason to believe the person operating the ride wasn’t paying attention Saturday afternoon when the incident happened on the King’s Crown ride at a Cinco de Mayo festival in Omaha.

The girl was taken to Nebraska Medicine — Nebraska Medical Center where she underwent surgery to repair her scalp.

Johnson says investigators are looking at the restraints on the ride.
