Police arrested the managing partner of local accounting firm PKF Pacific Hawaii on Sunday on suspicion of first-degree theft and money laundering.
Patrick Oki, 45, was arrested at the Honolulu Airport at 10:50 a.m.
PKF underwent a major restructuring last year after the departure of two partners and other key personnel.
Oki, a certified fraud examiner, also serves as the treasurer of Ahahui Koa Anuenue, the nonprofit fundraising arm of University of Hawaii athletics, and is a past president of the University of Hawaii Alumni Association. He was also an executive board member of the Boy Scouts of America Aloha Council.
Police charged Oki with four counts of first-degree theft and three counts of money laundering. It was unclear Sunday how the charges relate to his enterprises.
He was released after posting $250,000 bail.
