Race car driver Joe Ryan Osborne was arrested on Saturday night after a crash on track appears to have led to a violent reprisal in the pits.

Osborne got into it with another unnamed team at the infamous circle track. The unnamed team’s crew approached Osborne in the pits after the race, then Osborne whipped a donut and flung one of the rival crew members into the air, as local reports.

The official charges made by the Winston-Salem Police Department are as yet unknown.
