SEOUL, March 14 (Xinhua) -- Former South Korean President Lee Myung-bak was being questioned by prosecutors Wednesday for a string of corruption charges including bribery, embezzlement and tax evasion.
Lee, who ended his five-year presidential term in February 2013, appeared in the Seoul Central District Prosecutors' Office Wednesday morning as a "criminal suspect," local TV footage showed.
Before going inside the prosecution office, Lee read a brief statement to say sorry for worrying the people of South Korea. He hoped that he would be the country's last president in history to be investigated by state prosecutors.
Lee became the latest South Korean leader to be grilled by prosecutors over the corruption allegations.
Park Geun-hye, Lee's successor, was removed out of office last year for an influence-peddling scandal involving her longtime friend Choi Soon-sil.
Park was grilled by prosecutors in March last year and taken into custody later in the month. She is now standing trial, with prosecutors requesting 30 years in jail. A Seoul court is set to hand down a ruling next month.
Lee was reportedly being questioned at the same room of the prosecution office as the one for Park a year ago on allegations that he had received tens of millions of U.S. dollars in bribes from the country's intelligence agency and big companies including Samsung Electronics.
Samsung is believed to have paid retaining fees, on Lee's behalf, in the United States for DAS, a South Korean auto parts maker which Lee allegedly owns under the names of his relatives. DAS is under investigation for embezzlement and creating a slush fund, which is believed to have been funneled into Lee for his presidential campaign.
In return for the legal fee offer, Samsung Electronics Chairman Lee Kun-hee is believed to have bought a presidential pardon in 2009 when the Samsung chairman, currently being in hospital, got a suspended jail sentence for tax evasion.
The National Intelligence Service (NIS), the country's spy agency, is believed to have delivered secret operation fund to Lee's office at his behest through his closest aides, some of whom already admitted the allegation.
Prosecutors raided the offices and homes of Lee's relatives and aides, many of whom were summoned for questioning.
Lee is also suspected of dodging taxes through accounting fraud in DAS and by owning real estate assets and bank deposits under borrowed names.
