No, that incident took place at the 2008 Grand National Party convention where they were electing its directors and he was trying to pay-off other party members $2500 each to support his bid for the party director's seat. Unfortunately, the one who received the money envelop immediately turned it over to the justice department prosecutors. It was a party convention election electing party officers and not a general election, but the man's career was ruined because of that $2500 envelop.Just recently there was another corruption scandal in SK relating to election grafting.
One thing about Korean politicians is that they are wary of receiving any money for the fear that could instantly end his/her career, hence that parliamentary member turned his fellow party official in. Because the opposition and the press really dig dirt on candidates when they run for public office or be nominated as ministers.
