A special prosecutor will again summon Samsung Group’s Jay Y. Lee over allegations including bribery and embezzlement, potentially dealing another blow to South Korea’s biggest business empire after a court rejected its request to issue an arrest warrant last month. Lee, the de facto head of the Samsung Group and vice chairman of Samsung Electronics Co., will be summoned Monday morning, along with two other executives including Samsung Electronics President Park Sang-jin, Lee Kyu-chul, a spokesman for the prosecutor’s office, told reporters in a televised briefing on Sunday.
