TOKYO, Sept 21 (Reuters) - A consortium led by private equity firm Japan Industrial Partners (JIP) acquired 78.65% of Toshiba through a tender offer, the company said, coming a step closer to completing the $14 billion deal to take the company private.

Ownership of more than a two-third majority would be enough for the JIP group to squeeze out remaining shareholders. Toshiba is now set to be delisted as early as December, ending its 74-year history as a listed firm. (Reporting by Makiko Yamazaki; Editing by Kim Coghill)
