Former South Korean President Moon Jae-in has called his bribery indictment “unjust” and accused prosecutors of abusing their power in what he called a politically motivated investigation.

South Korean prosecutors indicted former president Moon Jae-in for alleged bribery on Thursday, making him the latest former leader of the country to face legal troubles in a case linked to the appointment of his then son-in-law at a Thai airline.

Prosecutors have indicted former South Korean President Moon Jae-in on charges of bribery related to his former son-in-law's job at an airline. Prosecutors argue his former son-in-law, identified only by his surname Seo, had little experience in the aviation industry but was hired in exchange for the airline's CEO leading a state-funded agency.
