Investigators from the Seoul Central District Prosecutors' Office stormed the home and office of Lee Sang-joo, who is married to Lee Myung-bak's eldest daughter and works as a senior executive for Samsung Electronics, reports Xinhua news agency.
Lee Sang-joo was suspected of receiving bribes from an unidentified third party on behalf of the former president.
The prosecution's investigation into Lee Myung-bak has been underway over corruption allegations involving DAS, a domestic auto parts manufacturer.
Lee Si-hyung, the son of the former leader and a DAS executive, was summoned and grilled on Sunday by prosecutors as part of the prosecution's probe into the corruption allegations.
Prosecutors have planned planned to summon the former president early next month.
