A U.S. national wanted by the Federal Bureau of Investigation over a bitcoin scam has been arrested in Indonesia and charged under a child protection law for suspected sex crimes, Indonesian police said on Tuesday.

Russ Albert Medlin was arrested at his residence in Jakarta on Monday after police questioned three minors, and he was suspected of sex crimes, Jakarta police spokesman Yusri Yunus said.

Indonesia’s child protection law carries a maximum penalty of 15 years in prison.

Another police officer said that Medlin could also face extradition to the United States.

Medlin has been on an Federal Bureau of Investigation (FBI) wanted list for crimes related to an investment scam in bitcoin stocks, Yunus said, adding the scam totaled $722 million.

Indonesian authorities said they were coordinating with the American embassy.
