Hong Kong-based Gandhara Master Fund had acquired 8.26 percent of Livedoor Co.'s outstanding shares by last Thursday, the day before the Internet company was delisted from the Tokyo Stock Exchange.
The fund's stake is higher than the 6.89 percent it had as of Feb. 27, according to a report filed Monday by the investment fund with the Finance Ministry's Kanto Local Finance Bureau.
Gandhara bought the additional shares on four different occasions from March 10 to last Thursday.
Livedoor's stock was removed Friday from the Mothers bourse for startups after a series of accounting fraud allegations created a scandal that brought its six-year presence as a listed company to an end.
The stock finished last Thursday's trading 7 yen lower at 94 yen, less than one-seventh of the 700 yen or so it fetched earlier this year.
