Baton Rouge - Authorities arrested a driver who led law enforcement on a chase over the Mississippi River. 

Beau Thomas Martin led Port Allen Police on a chase Friday afternoon. 

The West Baton Rouge Parish Sheriff's Office picked up the pursuit after he left the city limits.

Authorities say he led them as far as Brusly and eventually crossed the Old Bridge. Martin allegedly crashed into several cars driving into Baton Rouge. Martin bailed out of the car with a woman in Downtown Baton Rouge.

Police eventually captured Martin. Police say he originally identified himself as his brother, but police say they quickly discovered his actual name.
