(CHARLOTTE OBSERVER) — A nylon rope used to suspend Fox Sports’ overhead television camera came loose during Sunday’s NASCAR Sprint Cup series Coca-Cola 600, delaying the race by about 26 minutes and injuring at least 10 fans.

The incident happened 121 laps into the 400-lap race at Charlotte Motor Speedway. Long strands of the rope tangled some cars, causing damage to then-race leader Kyle Busch’s No. 18 Toyota and the No. 9 Ford driven by Marcos Ambrose.

The falling rope injured 10 fans, according to Charlotte Motor Speedway. Seven were treated and released at the track, while three were transported a local hospital for observation.
