A renowned human rights activist was found to have sexually harassed a young woman, sending shockwaves through local social networks.

Goh Eun-tae, professor of Chungbu University and a member of Amnesty International’s executive committee, allegedly sent the woman several inappropriate texts through mobile messenger “Kakao Talk,” according to the victim’s Twitter posts.

The 27-year-old woman claimed that Goh had sent sexual messages including “Send me nude parts of your body” and “I want to kiss the middle toe on your right foot.”

Shortly after the woman’s posts went viral on Twitter, Goh issued a formal apology on his Twitter account and admitted that he sent such messages. Goh said he “will have time for self-reflection” and then deleted his Twitter account which had about 40,000 followers.

The two have known each other since September last year and shared contacts in a forum where Goh gave a speech about human rights. The problematic mobile exchange lasted for a week.

The 50-year-old professor graduated from Seoul National University and served as chairman of the Korean chapter of Amnesty International. The human rights organization is considering punitive measures against him, including permanent expulsion from the organization.
