CONCORD, N.C. Officials at the Charlotte Motor Speedway say that 10 fans were injured when a nylon rope fell over the grandstands in turn four on lap 121 of the Coca-Cola 600.

Officials said that three people were transported to the hospital for evaluation.

The rope was a guide for a network television overhead camera.

An NBC Charlotte crew at the race at the time of the crash said it was not immediately clear what happened until the race was stopped due to the roaring race engines.

The Coca-Cola 600 was at a standstill for nearly 30 minutes as workers tried to remove pieces of the cable from the track.

According to a report by USAToday, the cable damaged race cars traveling 195 mph. Race leader Kyle Busch had some of the worst damage.

Reportedly, seven fans were treated at the track and three were taken to a hospital.

The camera cable belonged to Fox Sports, who released the following statement:

At this time, we do not have a cause for the failure of the camera drive line that interrupted tonight's Coca-Cola 600 at Charlotte Motor Speedway, and our immediate concern is with injured fans.

The camera system consists of three ropes -- a drive rope which moves the camera back and forth, and two guide ropes on either side. The drive rope failed near the Turn 1 conncection and fell to the track. The camera itself did not come down because guide ropes acted as designed. A full investigation is planned, and use of the camera is suspended indefinitely.

This camera system had been used successfully at this year's Daytona 500, last week's NASCAR Sprint All-Star Race and other major events around the world. We certainly regret that the system failure affected tonight's event, we apologized to the racers who cars were damaged and our immediate concern is for the race fans. We also offer a sincere 'thank you' to the staff at Charlotte Motor Speedway for attending to the injuries and keeping us informed on this developing situation.
