A former Kaesong Industrial Complex (KIC) businessman attempted suicide on Tuesday by swallowing sleeping pills, local media reported on Wednesday.

Identified only by his surname Yang, the KIC entrepreneur survived but was hospitalized in Ansan, Gyeonggi Province. Yang has reportedly since left the hospital and returned home.

Yang is one of many South Koreans to have lost their businesses at the KIC when North Korea seized all assets at the complex, after Seoul’s decision in early February to pull all staff from the KIC in protest over the North’s fourth nuclear test in January and satellite launch a few weeks later.
