Immigration police chief Lt. Gen. Panu Kerdlarppol said Hamza Bendelladj was arrested Sunday night during a layover at Thailand's international airport while traveling from Malaysia to Egypt. He and his family had been on vacation in Malaysia, he said.

Panu said on Monday that police confiscated two laptops, a tablet computer, a satellite phone and a number of external hard drives from Bendelladj, 24.

He said the FBI had been pursuing Bendelladj for nearly three years. U.S. authorities believe the suspect hacked private accounts in more than 217 banks and financial companies worldwide, causing about $10 million in losses per transaction, he said.

Panu said Bendelladj will be extradited to the U.S. state of Georgia, where a district court has issued an arrest warrant.
