South Korean prosecutors have sought an arrest warrant for ousted president Park Geun-hye, they said, days after questioning her over the corruption and abuse of power scandal that brought her down.
Park, 65, had her removal from office confirmed by the country's top court earlier this month, ending her executive immunity, and her prosecution has been a key demand of the millions of people who took to the streets to protest against her.
The former president is accused of multiple offences including bribery, leaking government information, and abuse of power in the scandal.
"The accused abused her enormous power and status as president to receive bribes from companies or to infringe upon the rights to freedom of corporate management and leaked important confidential information on state affairs. These are grave issues," the prosecutors said in a statement on Sunday.
"A large amount of evidence has been collected so far but the accused is denying most of the charges, and there is a risk of destroying evidence in the future," it said.
Choi Soon-Sil, Park's secret confidante at the heart of the scandal, is already on trial for forcing top local firms to "donate" nearly $70 million to non-profit foundations she allegedly used for personal gain.
Prosecutors said it would be "counter to the principle of fairness" if Park was not arrested.
If Seoul Central District Court approves the warrant, Park will become the third former leader to be arrested over corruption in Asia's fourth-largest economy, where politics and big business have long been closely tied.
Two former army-backed leaders who ruled in the 1980s and 1990s - Chun Doo-Hwan and Roh Tae-Woo - both served jail terms for charges including bribery after they retired.
Park has been named as Choi's accomplice for allegedly offering governmental favours to top businessmen who enriched her friend, including Samsung heir Lee Jae-Yong, who was arrested last month and charged with bribery last month.
She is also accused of letting Choi, a high school graduate with no title or security clearance, handle a wide range of state affairs including nomination of top officials.
The former president has denied any legal wrongdoing. She apologised for putting trust in Choi, but said she only let her edit some of her presidential speeches and provide the president with some "public relations" help.
Park, daughter of late dictator Park Chung-Hee, is also said to have ordered aides to leak secret state files to Choi, and to have cracked down on thousands of artists who had voiced criticisms of her or her father's rule from 1961 to 1979.
Park was elected in 2012, largely thanks to a bedrock of support among older, conservative voters who benefited from rapid economic growth under her father's rule.
