Australian teen accused of plotting terror attack in Sydney

Officials believe he was working alone, and his arrest means there is no longer any threat to public safety linked to the alleged plot, Gaughan said.

[...] the teen had been under police surveillance, Attorney-General George Brandis told reporters.

Police have since conducted dozens of raids they say have been aimed at thwarting multiple terror plots around Australia, including an alleged plan to attack government buildings and a naval base in Sydney.
