Park left Seoul's presidential complex yesterday, two days after the Constitutional Court upheld her impeachment by parliament and stripped her of executive power and privileges.
"It will take time but I believe that the truth will eventually be revealed," she said through a spokesman after arriving at her private home in Seoul -- her first remarks since the ruling.
TV footage showed a broadly smiling Park waving to hundreds of supporters who gathered around her home, taking selfies with some as many chanted "Our president forever!"
Thousands of her supporters staged protests in Seoul after the court verdict, with violent clashes leaving three protesters dead and dozens including police and journalists wounded.

In an editorial, the centre-right JoongAng Ilbo daily accused her of trying to incite her remaining supporters and hampering an impending probe into allegations against her.
"Park Geun-Hye's defiance -- is she trying to break the nation into two?" it asked.
Park has been named as an accomplice to the secret confidante at the heart of the corruption and influence-peddling scandal that triggered her dramatic downfall.
Park is accused of offering policy favours to businessmen who paid Choi, including the heir to the smartphone giant Samsung, Lee Jae-Yong, who has been indicted for bribery and other offences.
A new presidential election must be held by early May, and opposition politicians urged Park's investigation.
"To the last, Park did not say a single word of apology and only talked of the so-called truth in apparent disobedience of the ruling," said Choo Mi-Ae, leader of the main liberal opposition Democratic Party (DP).
Moon Jae-In, a former DP lawmaker and the presidential frontrunner, described Park's remarks as an "unacceptable" bid to paint the court as flawed.
"This is an unacceptable behaviour, after her scandal left the country's reputation deeply tarnished and South Koreans deeply traumatised," he said.
Another opposition group, the People's Party, slammed Park for "showing zero willingness" to honour the Constitution and urged her to cooperate with prosecutors.
