Two former aides to President Lee Myung-bakaccused of playing key roles in a spying scandal that is rocking Koreahave been arrested.
Arrest warrants for former presidential secretary Lee Young-ho and former presidential labor advisor Choi Jong-seok were issued late Tuesday because of worries they might destroy evidence.
The two men are suspected of ordering Jang Jin-su, a former official in the Prime Minister's Office, to delete computer files related to the illegal surveillance of civilians by the office in July 2008 after the prosecution began investigating the case in 2010.
Jang has claimed that both men gave him money to keep his mouth shut over the destruction of evidence.
Prosecutors say they will trace the origin of the 50-million won delivered to Jang, which he says was sealed as if money has been freshly printed.
