SEOUL (Reuters) - Ousted South Korean president Park Geun-hye apologized to the country on Tuesday as she appeared at prosecutors’ offices for questioning as a criminal suspect in a corruption scandal that has gripped the country for months.

Park, 65, became South Korea’s first democratically elected president to be removed from office when the Constitutional Court this month upheld her impeachment by parliament in December.

She has been accused of colluding with a friend, Choi Soon-sil, to pressure big businesses to donate to two foundations that backed her policy initiatives. Park and Choi have both denied wrongdoing.

“I am sorry to the people. I will faithfully cooperate with questioning,” Park said in front of media at the steps of the prosecutors’ office building, her first comments directly to the public since she was dismissed.

The questioning ended 14 hours later, just before midnight, according to Sohn Bum-kyu, one of Park’s lawyers. Park is expected to head home after reviewing her statements made to the investigators early on Wednesday.

Park has not been charged but could face more than 10 years in jail if convicted of receiving bribes from bosses of big conglomerates, including Samsung Group chief Jay Y. Lee, in return for favors.

After about five hours of questioning, an official from the prosecutors’ office told reporters Park had been forthcoming but he declined to elaborate on what she had been asked, on her responses or on what charges she might face.

Park’s fate and the widening corruption investigation have gripped the country at a time of rising tension with North Korea and China.

Hundreds of Park’s flag-waving supporters gathered outside her home in Seoul’s upmarket Gangnam district to see her off, and later gathered outside the prosecution office.

Park was dressed in a dark navy coat and trouser suit with grey shoes, and looked somber as she stood to deliver her brief remarks.

“EQUAL BEFORE THE LAW”

Park, who was accompanied by two of her lawyers, was given tea before her first session of questioning by two prosecutors and an investigation official, prosecutors said in a statement.

One of her lawyers, Yoo Yeong-ha, is known as her “Bulletproof Vest” and has been her legal voice since the beginning of the scandal in October.

Park declined to have her questioning recorded by video camera, prosecutors said.

She later had a lunch break of some seaweed rice rolls and a sandwich, one of her lawyers said. Later in the day, she took another break for dinner brought in from a nearby restaurant.

The official from the prosecutors’ office declined to say if she would be summoned again or whether a warrant for her arrest would be filed.

Sohn, one of Park’s lawyers, said her health was not at its best and she had been getting medical checks between questioning sessions. The prosecution official said his office had not received any medical note regarding her health.

The scandal has undermined support for Park’s conservative ruling party. A liberal opposition politician, Moon Jae-in, is leading in opinion polls and is expected to win a snap presidential election on May 9.

Park’s supporters and opponents have held protests in Seoul for months but police have managed to keep them apart and no serious violence has broken out between them.

A spokesman for Moon said uncovering the truth would help heal divisions.

“We want former president Park to tell the truth and ask for forgiveness. All are equal before the law,” said the spokesman, Park Kwang-on. “Finding the truth is a first step for the unity of the people.”

A top official from Park’s party urged prosecutors not to be swayed by public opinion but to find the truth and give Park the cordial treatment a former president deserved.

“Everyone, not only me, is feeling miserable and distressed,” the party official, Chung Woo-taik, told a meeting.

A Danish court will rule on April 19 on an extradition appeal by Choi’s daughter Chung Yoo-Ra, who is wanted for questioning in relation to the scandal, Denmark’s public prosecutor said on Tuesday.
