By Ju-min Park and Se Young Lee SEOUL (Reuters) – A South Korean judge questioned Samsung Group leader Jay Y. Lee behind closed doors on Wednesday to decide whether he should be arrested over his alleged role in a corruption scandal that led parliament to impeach President Park Geun-hye. Lee, 48, in dark overcoat and purple necktie, did not answer questions from reporters as he left the Seoul Central District Court after the nearly four-hour hearing and headed by car to a detention center to await his fate. One of the five attorneys representing Lee struck a positive tone, saying the legal team had argued its case sufficiently.
