Robert Downey Jr.'s son was arrested yesterday (06.29.14).
The 'Iron Man 3' actor's oldest child Indio, 20, was arrested in West Hollywood when police noticed he was smoking something out of a pipe in a vehicle he was passenger in.
After a Los Angeles County Sheriff's deputy pulled the car over, they allegedly found cocaine in Indio's possession.
Indio - whose mother is the actor-s ex-wife Deborah Falconer - was booked for possession of cocaine and released from jail just after midnight after posting $10,000 bail.
The 'Sherlock Holmes' actor - who also has a two-year-old son Exton with wife Susan Levin - previously battled drug addiction himself and was arrested numerous times in the 1990s on drug-related charges.
Downey has previously spoken of how he felt "safe" in prison.
He said: "When the door clicks shut, then you are safe. There is nothing aside from a rogue correctional officer that can do you harm if you have the right cellie. You are actually in the safest place on Earth. Safe from the intruders. From anything that might thwart the mortal coil."
