SYDNEY, Australia — The Australian authorities on Wednesday raided the home of a computer expert and entrepreneur in suburban Sydney, just hours after two news outlets identified the man as a likely creator of the digital currency Bitcoin.

The Australian Federal Police said the raid on the residence of the man, Craig Steven Wright, was for a tax investigation, and a spokesman said it had no connection to the Bitcoin reports. The Australian Taxation Office, which asked the police to carry out the raid, declined to comment on “any individual’s or entity’s tax affairs.”

The raid, in the leafy suburb of Gordon on Sydney’s upper north shore, came hours after reports in Wired magazine and Gizmodo drew strong links between Mr. Wright and Satoshi Nakamoto, the pseudonymous creator of the virtual currency that has grown to billions of dollars in total value.
