The South Korean special prosecutor’s office said on Thursday it “deeply regrets” a court ruling to deny its request to arrest Samsung Group [SAGR.UL] leader Jay Y. Lee and said it will continue its investigation into the graft scandal involving President Park Geun-hye. “We will consider necessary measures and continue with the investigation without wavering,” special prosecution spokesman Lee Kyu-chul told reporters during a briefing, without elaborating. The Seoul Central District Court earlier on Thursday dismissed a warrant to arrest the 48-year-old Lee, who was named a suspect as part of an investigation into the political scandal that has led to the impeachment of President Park.
