(VOVworld) - A former presidential secretary was arrested Sunday after he resigned over alleged involvement in the latest political scandal surrounding President Park Geun-hye's confidante.

An Chong-bum, a former senior presidential secretary, is being taken to a detention center in southern Seoul on Nov. 4, 2016

The Seoul Central District Court issued a warrant to formally arrest An Chong-bum on suspicions of abuse of authority and attempted coercion. The former senior secretary for policy coordination has been in custody since late Wednesday after hours of questioning by prosecutors over a string of allegations. Prosecutors suspect that An collaborated with Choi Soon-sil, longtime friend of Park and the woman at the heart of the scandal, to pressure local companies to donate nearly 80 billion won (70 million USD) to two nonprofit organizations.

The latest arrest came less than two days after President Park Geun-hye apologized for a second time in a nationally televised address, saying she will accept, if needed, a probe regarding her role in the alleged wrongdoings.
