South Korean police raided the attacker's home and office on Wednesday in the city of Asan. Authorities also intend to search the assailant's phone.

The attack left a gash in Lee's neck that is about 1 centimeter long, according to YTN television.

Min told the press that the knife cut Lee's jugular vein, requiring stitches to close the bleeding wound.

A neighbor living near the unidentified suspect told The Associated Press that the man was a quiet person who did not often talk about politics. 

He also said the suspect works as a real estate agent but fell behind on paying his rent.
