Australian police arrest teen accused of plotting to detonate bombs

Police arrested a 17-year-old and accused him of plotting to detonate three homemade bombs in the Australian city of Melbourne, officials said on Saturday, in the latest terrorism scare involving a teenager.

The teen was arrested on Friday afternoon in a joint federal-state police counterterrorism operation at his home in the upmarket suburb of Greenvale where the explosive devices were found, Australian Federal Police Deputy Commissioner Mike Phelan said. The state police bomb squad rendered the devices safe, he said.

Melbourne is Australia's second largest city and is the capital of Victoria state.

Last month, five Australian teenagers were arrested on suspicion of plotting an Islamic State in Iraq and Syria group-inspired attack at a Veterans' Day ceremony also in Melbourne that included targeting police officers.

"It's deeply troubling to police that such young people in our community are becoming disaffected in the way in which they are and considering endangering the lives of many Australians," Phelan told reporters.

There were "no links at all" between that latest suspect and those arrested last month, Phelan said. Police were investigating whether the latest plot had been inspired by ISIS.

Phelan said he could not confirm a media report that the plot would have targeted a charity run in Melbourne on Sunday to mark Mothers' Day in Australia.

"We've got to examine lot of material that was seized at the premises, sift through a lot of intelligence, we have to get the full picture so we may not know exactly where it was going to occur nor when it was exactly going to occur, but let me tell you something was going to happen," Phelan told reporters.

He added: "As a result of the Victoria police and AFP interception yesterday, some Victorians are going to be alive because of it. Had we not intervened, there was a real threat of action being taken."

Bombs 'very rudimentary'

The suspect will appear in the Melbourne Children's Court on Monday on terrorism charges. His identity cannot be revealed for legal reasons.

Police had contained the plot and there was no further threat from the suspect or his colleagues to the people of Victoria, Phelan said.

The teen was driving from his home with a woman when he was stopped by police, Victoria Police Deputy Commissioner Bob Hill said. Police then ordered three occupants of the house to come outside, he said. Media reported they came out with their hands up.

The boy's father is reportedly a doctor of Syrian background. The family was unaware that bombs were stored in their two-storey home.

Hill said "his family are a caring, loving family that are now very, very distraught as a consequence of what is alleged."

"It has undoubtedly taken them by surprise," Hill said.

Phelan described the homemade bombs as "very rudimentary." Their destructive capacity had yet to be assessed, he said.
