Lee, the chief of the main opposition Democratic Party, was brutally attacked while visiting the southern port city of Busan on Tuesday.
The suspected attacker appeared to be a man in his 50s or 60s who wore a paper crown with Lee's name printed on it, news photographs showed. He approached Lee asking for an autograph among a crowd of supporters before he lunged forward and attacked, video footage showed.
The assailant was quickly subdued and arrested at the scene. His motive remains unknown.
