A man who broke the external window of a KBS studio with a pickaxe during a live radio program this week has been arrested. 

The Seoul Southern District Court on Thursday issued an arrest warrant against the 47-year-old man, surnamed Lee, on charges of property damage and obstruction of business.  

In issuing the warrant, the court said Lee is a flight risk and could possibly destroy evidence.  

Lee caused a commotion when he broke the window of an open KBS studio in Yeouido, Seoul, with a pickaxe at around 3:42 p.m. on Wednesday. He was shortly brought under control by the police and KBS security guards.
