A Hawaii man pleaded guilty Tuesday to using Robert Allenby’s credit cards after the Australian golfer said he was robbed and beaten in Honolulu.

Allenby recounted a bizarre saga in January that involved having no memory of what happened for two-and-a-half hours after he left a Honolulu restaurant. He went to dinner, and said he later woke up in a park with a bloodied face.

Owen Harbison was arrested in February on charges of identity theft, attempt theft and unauthorised possession of confidential personal information.

As part of a plea deal, Harbison agreed to a five-year prison term, Deputy Prosecuting Attorney Jacob Delaplane said. Sentencing is scheduled for August 12.

Harbison used Allenby’s credit cards and ID around Honolulu to buy gift cards, clothing and jewelery, Delaplane said. The total amount spent wasn’t available.

It’s still unclear what happened to Allenby after he left Amuse Wine Bar. Harbison is the only person who has been arrested in connection with the case.

The saga generated interested when Allenby took a photo of his scraped and bloodied face and posted it to his Facebook page after he got back to his hotel. He first said he was beaten, robbed and thrown from the trunk of a car. He later said he was told that by a homeless woman who helped him escape from a park.

One homeless man previously told the Honolulu Star-Advertiser that Allenby injured himself by passing out and hitting his head on a rock.

Allenby said in a text message that he would wait until the sentencing before commenting.
