LOS ANGELES (AP) — Robert Downey Jr.'s son will enter a drug diversion program to resolve a cocaine possession case filed after he was arrested earlier this year.

Indio Downey pleaded guilty to cocaine possession and was ordered to enter a diversion program that will result in his case being dismissed if he successfully completes it.

Indio Downey's attorney Blair Berk says her client will spend 90 days in a residential drug treatment program. Berk says he already has completed 70 days.
