The Seoul Central District Court on Friday said Choi Soon-sil "committed so many illegal activities" as she pressured Ewha Womans University to grant admission and then provide academic favors to her daughter despite Chung Yoo-ra's questionable qualifications.

Choi is being tried separately over more serious charges, including allegations that she colluded with Park to take tens of millions of dollars from the country's largest companies in bribes and through extortion.

Park was removed from office and charged over the corruption scandal in March.
