Australian authorities say they’ve honed in on a suspect in the bomb hoax that gripped the country on August 3rd.

18-year-old Madeleine Pulver, daughter of a millionaire tech exec, spent ten hours with what authorities believed was an elaborate collar bomb around her neck.

The case has been considered an extortion attempt since the beginning.

Now -- police believe they’ve found the man behind it -- in an unexpected place. Here’s CBS.

MARK STRASSMAN, CBS NEWS: “Outside Louisville, Kentucky, FBI SWAT teams arrested a suspect in a bizarre bomb plot case …50-year-old Paul Peters, charged in the attempted extortion in one of Australia’s richest businessmen. …Australian inspectors eventually tracked Peters to an apartment complex in LaGrange, Kentucky, the home of his ex-wife.”

Peters is reportedly in FBI custody.

Details of the investigation are still being kept mostly under wraps - but Australia’s The Daily Telegraph has the general storyline.

“It is understood police began tracing the electronic trail of the extortionist, leading them to a recent access to the gmail account at the library. As a result police were able to identify the suspect, who had already left the country for the United States on August 8, and conducted a search of the library last week, reportedly seizing a computer.”

In their report -- the team at ABC’s Good Morning America note one interesting twist in the case of the extortion note left with Madeleine Pulver.

SHARYN ALFONSI, ABC NEWS: “Apparently the two-page note attached to the bomb around Madeleine’s neck was signed ‘Dirk Struan.’ Turns out that’s the name of a character in a James Clavell novel, Tai-Pan. That story is about one businessman trying to destroy another businessman.”

ROBIN ROBERTS, ABC NEWS: “More twists and turns here.”

So what happens now?  A correspondent for ABC Australia explains.

LISA MILLAR, ABC NORTH AMERICA CORRESPONDENT: “Australian authorities want to extradite him as soon as possible but the court proceedings in New South Wales, but that process could take up to 60 days.”

Authorities say they do not believe Peters’ ex wife was involved in the plot, and she was not home at the time of his arrest.
