Another cryptocurrency exchange in Japan has been hit by a major theft.

BITPoint Japan Co. lost about 3.5 billion yen ($32.3 million) in virtual currencies after its online holdings were illegally accessed.

The exchange's operator, Remixpoint Inc., which provides a range of financial services, announced the theft on July 12.

Officials at the exchange detected a suspicious flow of Bitcoin, Bitcoin Cash, Ethereum, Litecoin and Ripple at about 10:10 p.m. on July 11.

They confirmed the theft about four hours later the next day, and by 10:30 a.m. had halted all transactions and currency exchange.

The incident follows the theft of 6.7 billion yen from the Zaif exchange, operated by Tech Bureau Corp., in September 2018.

About 2.5 million yen of the total amount lost by BITPoint Japan were customer assets, with the remainder belonging to the exchange operator.

The exchange said it would compensate customers for their losses.

The exchange operator received an improvement order from the Financial Services Agency in June 2018. The company had been making efforts to strengthen internal controls and business management practices and its period of submitting reports to the agency ended in June 2019.
