RockDoctor writes "Reports indicate that a suspect has been arrested in the Australian 'collar bomb' hostage/extortion case. The allegation is that the suspect had set up a Gmail account, through which he (allegedly) planned to communicate with the extortion victims and arrange delivery of the payment. Unfortunately for him, records were kept showing the location and time the account was set up, and also for a number of accesses. This information, combined with 'CCTV footage and motor vehicle records,' allowed the police to put an identity to the suspect, and arrange for his arrest. So, if you're planning an extortion scheme, don't drive your car to the internet cafe, don't set up the account from an airport, wear anonymous clothes (like Jason Bourne does?) and do all your accesses through hacked shell accounts somewhere in Outer Mongolia. But, this being Slashdot, everyone knew that already."
