Police: Aussie teen not attached to bomb

SYDNEY - Australian police say a suspicious device that was attached to a Sydney teen contained no explosives.

New South Wales state Police Assistant Commissioner Mark Murdoch said Thursday that someone attached the device to 18-year-old Madeleine Pulver as part of an elaborate hoax.

Pulver spent 10 horrifying hours attached to the device in her suburban Sydney home as a bomb squad tried to figure out if it contained explosives.

Murdoch said a person wearing a disguise entered the woman's suburban Sydney home on Wednesday afternoon and attached the device to her body. Officials spent 10 hours working to free her.

Murdoch said the woman is doing well.

No one has been arrested.

The device had appeared "very elaborate, very sophisticated," police said earlier in the day.

Police said they did not consider it a case of "self-harm" and that the woman tried vigilantly to help police since she called them to her home about 2:30 p.m. in the wealthy suburb of Mosman.

The woman has not been identified as Australian law enforcement very rarely release names of victims or suspects in criminal investigations. Australian media reported her father is an executive with a technology company, and is considered one of the country's richest men.
