The prosecution raided the headquarters of Samsung Electronics in Seoul's Seocho district on Tuesday as part of its investigation into the expanding Choi Soon-sil scandal.
The prosecution's special investigation team searched the offices of the company's external affairs division and other related departments since 6:40 a.m. The team is said to have secured documents related to the Korea Equestrian Federation(KEF) as suspicions swirl that Samsung was a "corporate sponsor" of Choi's dressage athlete daughter Chung Yoo-ra.
The prosecution has been investigating allegations that Samsung extended about three-point-five billion won to a company now known as Widec Sports established by Choi and her daughter.
In the latest raid, prosecutors also targeted the office of Samsung Electronics President Park Sang-jin, who currently serves as the president of the Korea Equestrian Federation.
