Michael Madsen Arrested
According to L.A. County Sheriff's spokesman Steve Whitmore ... a citizen first spotted Madsen driving erratically on PCH in Malibu around 2:50PM PT and called cops.
We're told responding deputies witnessed Madsen weaving through traffic -- in a Pontiac GTO with a red flame paint job -- and when they pulled him over they smelled alcohol.
Whitmore tells TMZ Madsen was arrested on suspicion of DUI after he performed poorly on a field sobriety test.
Whtimore says Madsen submitted to a breathalyzer test after his arrest ... and blew an outrageous .20. The legal limit in California is .08.
We're told Madsen's bail has been set at $15,000. He remains in custody ... just like his hot rod GTO, which was towed away from the arrest scene.
Update: Madsen's attorney Perry Wander tells TMZ ... the actor wants to assure his fans that he did not fail the field sobriety test and "believes that the breathalyzer test is flawed."
Wander says Madsen insists the whole thing is just a big misunderstanding. more on this story
