By Ju-min Park and Se Young Lee SEOUL (Reuters) – South Korea's special prosecutor on Monday sought a warrant to arrest the head of Samsung Group [SAGR.UL], the country's largest conglomerate, accusing him of paying multi-million dollar bribes to a friend of President Park Geun-hye. Investigators had grilled Samsung Group chief Jay Y. Lee for 22 straight hours last week as a suspect in a corruption scandal, which last month led to parliament impeaching Park. The special prosecutor's office accused Lee of paying bribes total 43 billion won ($36.42 million) to organizations linked to Choi Soon-sil, a friend of the president who is at the center of the scandal, in order to secure the 2015 merger of two affiliates and cement his control of the family business.
