Authorities in Thailand are investigating 16 citizens with reported ties to offshore companies set up by a Panama-based law firm.

The Anti-Money Laundering Office said Thai politicians and business figures were among those being investigated but did not name anyone at a news conference Friday.

The agency's secretary-general, Seehanat Prayoonrat, said the 16 people were listed as directors or shareholders for companies set up by Mossack Fonseca. Documents leaked from the firm and published worldwide showed it helped thousands of individuals and companies from around the world set up shell companies and offshore accounts in low-tax havens.

Seehanat said AMLO was seeking confirmation on the names from authorities in Panama.

The agency focuses on money laundering but said it will share its findings with tax, banking and stock market authorities.
