From the Associated Press:An Australian investment banker has admitted that he chained a fake bomb to a young woman's neck in a bizarre extortion attempt last year that ended with his arrest in the Louisville area. Paul Douglas Peters' lawyer pleaded guilty on his behalf in Sydney to a charge of aggravated break and enter and committing a serious indictable offense by knowingly detaining Madeleine Pulver. Pulver was alone in her family's Sydney mansion in August last year when the 50-year-old Peters tethered a bomb-like device around her neck. Bomb squad police took 10 hours to remove it. Peters will appear in court on March 16 for a pre-sentencing hearing. It was not immediately clear what prison sentence he could face. Peters was arrested at his former wife's home in Oldham County last year.
