33-year-old jobless man has been arrested for allegedly making an online threat to kill the U.S. ambassador in Seoul.
The man allegedly left an English message vowing to "kill" Mark Lippert with "nuclear poisoning" on the website of the White House on July 8, police said in a statement.
The man, surnamed Lee, has denied the allegation. But police say they've found a draft of the online threat and records of access to the White House homepage on his laptop computer, according to the statement.
The allegations come just months after Lippert was attacked by another man who slashed him with a knife during a breakfast forum. Lippert suffered deep gashes on his face and arm in that attack in March and was treated at a Seoul hospital for five days.
