Feb. 24 (Bloomberg) -- The Philippines may sanction chief gambling regulator Cristino Naguiat, who allegedly received free hotel accommodations from Japanese billionaire Kazuo Okada, President Benigno Aquino told reporters today in Manila.

Naguiat “will be asked to explain himself,” Aquino said, adding that he may ask his cabinet officials to investigate. Wynn Resorts Ltd. has accused Okada, who is developing a gaming business in the Southeast Asian nation, of improperly giving more than $110,000 in payments and gifts to two Philippine gambling regulators. Naguiat this week said there was “nothing inappropriate” with the accommodations and referred to accepting them as “industry practice.”
