SEOUL, South Korea (AP) -- South Korea's president has apologized for a bribery scandal involving his brother and former aides.
Lee Myung-bak bowed deeply in a televised speech Tuesday and said he is embarrassed and frustrated by the scandal.
Lee's brother was arrested earlier this month for allegedly accepting half a million dollars from two detained bankers with the intention of using his influence to help them avoid punishment.
A Seoul court said that a former aide to the president was arrested Tuesday on suspicion of taking money from one of the bankers. Prosecutors are also investigating another former aide suspected of receiving gold from another banker.
The scandal is a major embarrassment for the ruling party ahead of a presidential election in December.
Lee's single, five-year term ends early next year.
