He was busted on misdemeanor suspicion of driving under the influence.
The arrest took place in Malibu at 8:04 a.m. Tuesday, when the third of Rick and Kathy Hilton's four spawn was pulled over on Pacific Coast Highway by a Los Angeles County Sheriff's deputy.
Barron Hilton was hauled off to the Lost Hills Station, where he was checked in at 8:35 a.m. Per his booking sheet, he weighed a lean 143 pounds and measured six-one.
According to Sheriff's Department spokesman Steve Whitmore, Hilton also blew a 0.14 percent blood-alcohol reading, almost double the state limit of 0.08—and that's for drivers over 21 years of age.
Best wishes.
