Boy 15, and four men charged with plotting terror attack in Australia

SYDNEY // A teenager and four men were charged Thursday with planning a terrorist attack on an Australian government building, part of an ongoing investigation into the alleged plot, police said.

A 15-year-old and 20-year-old man from western Sydney were arrested and charged with conspiracy to prepare for a terrorism act, said Michael Phelan, the Australian federal police’s deputy commissioner of national security. Three other men, already jailed on separate terror charges, were later charged with the same offence, police said.

All face a potential sentence of life in prison if convicted.

Officials said the arrests were not related to a new terror threat, but linked to a plot they uncovered a year ago that prompted a series of raids in Sydney in December 2014. That plot involved a plan to target a government building in Sydney, possibly a federal police building, Mr Phelan said. Those arrested Thursday had been under police surveillance since then, which led to the charges.

Mr Phelan was vague on details of the alleged plot, and said police were not sure exactly what role the teenager may have played in the planning, what the specific target would have been or how the attack was to be carried out.

Police believe the plot, and another one that would have targeted a random member of the public in Sydney, were influenced by extremists overseas, Mr Phelan said.

“A lot of the people we are dealing with — and emphasising this is only a small group of people — are clearly radicalised to the point of talking about and acting out with violence. How they’ve become radicalised, we don’t actually know,” he said.

Police have conducted a steady stream of raids across the country since the government raised the nation’s terrorism warning level in September 2014 in response to the domestic threat posed by supporters of ISIL.
