The Indonesian Attorney General's Office has arrested a chief judge of a local court on charges of bribery following the acquittal of three palm oil companies in a case related to corruption in obtaining export permits, an official said. A court had last month acquitted the three companies - Wilmar Group, Musim Mas Group, and North Sumatra-based Permata Hijau Group - of charges of misconduct in obtaining export permits in 2022. But Harli Siregar, the spokesperson for the Attorney General's Office, said on Saturday that two lawyers of the companies had allegedly paid Muhammad Arif Nuryanta, chief judge of South Jakarta district court, 60 billion rupiah ($3.57 million) to arrange for a favourable verdict.
