On Thursday, 2,000 armed Korean police officers surrounded a Buddhist temple where Han Sang-gyun, president of the Korean Confederation of Trade Unions, had been hiding for a month. Han was arrested for his involvement in a violent labor protest that happened a month ago. The temple is known for harboring "political dissidents". When Han stepped out of the temple to be arrested, he called for a general strike to begin on Wednesday. Han has also already planned another strike that will begin on December 19th.
