US Olympic gold medalist Sha'Carri Richardson arrested for speeding in latest legal struggle

U.S. Olympic sprinter Sha'Carri Richardson was arrested on a speeding charge after allegedly driving more than 100 mph in Florida Thursday.

Authorities said Richardson was driving 104 mph and dangerously passing other motorists on the highway.

It is the latest controversy in a growing series of off-track issues for the American gold medalist. 

In August, Richardson was arrested for allegedly assaulting her boyfriend, fellow American sprinter Christian Coleman, at the Seattle Tacoma Airport.
