Prosecutors quiz former vice-sports minister

South Korean prosecutors questioned a former vice-sports minister on Wednesday as their probe into the corruption scandal engulfing President Park Geun-hye spreads to preparations for the 2018 Winter Olympics.

Park is under pressure over her shadowy confidant Choi Soon-sil, who is accused of using her personal ties with the president to coerce major companies to donate millions of dollars to nonprofit foundations Choi then used for personal gain.

Kim Chong, who served as vice-sports minister for three years until last month, is accused of helping Choi's foundations win lucrative state contracts.
