Robert Downey Jr has released a statement following his son's recent arrest for cocaine possession.
The Iron Man 3 actor - who has famously battled with addiction in the past and was arrested numerous times in the 1990s on drug-related charges - believes his oldest child Indio, 20, "likely inherited" his weakness for substance abuse, but will hopefully overcome his issues.
Robert, 49, told Us Magazine: "Unfortunately there's a genetic component to addiction and Indio has likely inherited it. There is a lot of family support and understanding, and we're all determined to rally behind him and help him become the man he's capable of being.
"We're grateful to the Sheriff's department for their intervention, and believe Indio can be another recovery success story instead of a cautionary tale."
Indio was arrested in West Hollywood last night when police noticed he was smoking something out of a pipe in a car he was a passenger in.
