“We are investigating whether foreign entities or individuals paid local criminals in Australia to commit some of these crimes in our suburbs,” Australian Federal Police (AFP) Commissioner Rhys Kershaw said, adding that it was possible cryptocurrency was involved.
It may take longer to identify the digital currency, Mr. Kershaw said.
The commissioner said police are also investigating whether the youths committed the crimes and whether they were radicalized online.
However, Mr Kershaw warned that “intelligence is not the same as evidence” and more charges were expected soon.
Last week, a Sydney man became the first person to be charged with making death threats against a Jewish organization by a federal task force dubbed Special Operation Ovalit.
Albanese said Tuesday’s incident at a children’s center in Sydney’s eastern suburb of Maroubra was “as cowardly as it is disgusting” and called it a “hate crime”.
“It was an attack aimed at the Jewish community. And this is a crime that affects all of us, because it is also an attack on the nation and the society that we have built together,” he wrote on social media.
