Samsung chief Lee summoned again

Spokesman says prosecutors may seek arrest of other executives

Samsung Group leader Lee Jae-yong appeared at the South Korean special prosecutor's office for questioning on Monday as part of a wider investigation into an influence-peddling scandal that could topple President Park Geun-hye.

The special prosecutor has focused on South Korea's biggest conglomerate, accusing Lee in his capacity as Samsung chief of pledging $37.3 million to a business and organizations backed by Park's friend, Choi Soon-sil, in exchange for support for a 2015 merger of two Samsung companies.
