The South Jakarta district court on Tuesday kicked off the first trial of sex abuse on children at the prestigious Jakarta international school.
The court tried Agun Iskandar, a janitor at the school, said Saut Irianto Rajaguguk, lawyer of Agun.
"The court session today (on Tuesday) was close, it was just the reading of verdict," Rajaguguk said at the court.
Agun and four others janitors were alleged of implicating in sexual abuse on 6 year-old student at the school located in Pondok Indah of South of Jakarta.
The four janitors would be tried on Wednesday, according to the lawyer.
