She is set to become the fourth former South Korean leader to be questioned by prosecutors over corruption scandals.
Two former army-backed leaders, who ruled in the 1980s and the early 1990s — Chun DooHwan and Roh Tae-Woo — served jail terms for bribery after they retired.
Another ex-president, Roh Moo-hyun, killed himself by jumping off a cliff in 2009 after being questioned by prosecutors over suspected bribery.
The latest corruption and influence-peddling scandal is centred on Park’s close confidante, Choi Soon-sil, who is on trial for abuse of power and coercion.
Choi is accused of using her presidential ties to force local firms, including Samsung, to “donate” nearly US$70 million (RM311.4 million) to non-profit foundations she allegedly used for personal gain.
Park — the 65-year-old daughter of the late former strongman Park Chung-hee — has been named as Choi’s accomplice who helped her extract money from the firms.
The scandal that rocked the nation has seen the heir to electronics giant Samsung, Lee Jaeyong, arrested and charged with bribery for offering millions of dollars to Choi in return for policy favours from Park.
The former president is also accused of letting Choi, who has no title or security clearance, handle a wide range of state affairs, including nomination of top officials and diplomats.
Park voiced defiance over the court ruling, saying “the truth will eventually be revealed” through her spokesman after returning to her private home on Sunday.
The ouster of Park, who had commanded a huge following among older, conservative South Koreans who benefited from the rapid growth under her father’s 1961-79 rule, has sparked angry, sometimes violent, protests by her supporters. AFP
