Trevor Walker, a former reality TV star who appeared on Bravo's "Below Deck," has been arrested on felony DUI and other charges in Escambia County, Florida. He is accused of driving on a suspended license, committing a moving traffic violation, and misdemeanor theft. During his time on the show, Walker was demoted from senior deckhand by co-star Kelley Johnson after frequently arguing with her and falling out with his crewmates. He was released early Tuesday morning and is scheduled to appear in court later in April.
