A grandson of NASCAR founder Bill France was arrested on drug charges.

According to a Daytona Beach police report, J.C. France was arrested early Thursday morning on charges of possession of narcotics and driving under the influence. The report states that an officer found a small bag containing a "white cakelike substance" during a traffic stop.

France is the son of NASCAR board member Jim France and a driver in NASCAR's Grand-Am Series. According to a statement from NASCAR spokesman Ramsey Poston, he has been indefinitely suspended from all competition.

Poston says France is being treated "like any other competitor."

France posted $4,500 bond and was released from Volusia County jail on Thursday.
