The parliament's National Security Committee has also called an emergency meeting.
"The KNAB will comment on this matter and issue an explanation as soon as it will be possible to do so and will not hinder the investigation", the bureau's spokeswoman Laura Dusa said, quoted by BNS.
On Saturday evening, Latvian state TV showed Rimsevics arriving by auto to the anti-corruption agency and leaving hours later. Rimsevics's lawyer, Saulvedis Varpins, said that Latvia's chief monetary officer considered his arrest "clearly illegal", according to Leta news service quoted by Bloomberg.
The economy in the Baltic state, which gained independence from the Soviet Union in 1991 and shares a border with Russian Federation, has been booming in recent years.
The Latvian Central Bank is an independent institution and Rimsevics has been its head since 2001.
Latvia became the 18th member of the Eurozone on 1 January 2014.
Latvia's Economics Minister Arvils Aseradens, speaking on Radio Latvia, also said the governor should consider resigning.
Rimsevics' home and offices at the Bank of Latvia were both raided by authorities, but the country's Corruption Prevention Bureau gave no details about its investigation, or the nature of the raids. Treasury Department's Financial Crimes Enforcement Network, FinCEN, proposed sanctions against ABLV, Latvia's third largest bank, for laundering billions in illicit funds and allowing its clients to violate sanctions on North Korea. ABLV said in a statement in response on Tuesday that FinCen had referred to unfounded and misleading information about the bank.
