Bistus Entertainment issued a statement Tuesday acknowledging that its previous characterization of the allegations as “without basis” was premature. “First, we would like to address our previous statement that the allegations were ‘without basis.’ Following further verification, we have confirmed that a record does in fact exist listing Ahn Sang-ho, the actor's great-grandfather, as a council member of the Daejeong Friendship Association in 1916,” the agency said. The apology comes a day after the agency initially denied claims that Ahn’s great-grandfather was a pro-Japanese collaborator during Japan's colonial occupation of Korea. The controversy centers on Ahn Sang-ho’s activities during the Japanese colonial period, including his membership in the Daejeong Industrial Friendship Association, a pro-Japanese organization.
