BALI, Indonesia (AP) — A trial has opened for a 14-year-old Australian boy arrested on Indonesia’s resort island of Bali for allegedly possessing marijuana.

The boy, wearing a mask to protect his identity, arrived at Denpasar District Court with his mother on Tuesday for a brief, closed-door hearing.

Prosecutor I Gusti Putu Gede Atmaja says the teen faces up to 12 years in prison if found guilty of buying 3.6 grams of marijuana on Oct. 4.

The boy’s lawyer, Muhammad Rifan, says because he’s a minor and appears to have been purchasing the drug for personal use, not distribution, he could escape jail time.

Rifan says in the best case scenario he’ll be allowed to return home in the custody of his parents.

The trial, being closely watched in Australia, continues Friday.
