US journalist says there were concerns about Las Vegas track

British racing driver Dan Wheldon has been killed in a 15-car crash at the Las Vegas Indy 300 on Sunday.

The 33-year-old former series champion, who twice won the prestigious Indy 500, died when his car flipped into the air and hit a wall.

American journalist Quinn Klinefelter, from Detroit public radio station WDET, knew the Buckinghamshire-born star.

He told BBC Radio 5 live's Up All Night programme that concerns were raised before the race began about whether the track was able to accommodate a larger than normal field of 34 cars.
