South Korean authorities have indicted an activist for allegedly taking instructions from a North Korean agent and spying for Pyongyang while running for local office, according to a ruling party lawmaker.

People Power Party (PPP) lawmaker Yoo Sang-beom, a member of the National Assembly’s intelligence committee, stated on social media on Saturday that the activist is a member of a party that has had a seat in South Korea’s parliament and ran to be a provincial governor.
