Nick Stahl, a star of the HBO series Carnivàle, was arrested last night after LAPD vice officers working undercover allegedly caught him pleasuring himself inside a sex shop in Hollywood.

Police say the actor was inside the store's private porn-viewing booth committing a lewd act. He was booked for misdemeanor lewd conduct but released a short time later.

What's next for the LAPD? Well, they hear there's a lot of nudity in those other little booths that say "BATHROOM" on the door.
