White supremacist Jack Van Tongeren, who is accused of plotting to firebomb four Chinese restaurants in 2004 - has been arrested in Perth with another co-accused, after six weeks on the run.
The ultra right-wing Australian Nationalist Movement leader, Matthew Billing, skipped bail in February.
The pair, and a third co-accused, John Van Blitterswyk had been due to face trial in Perth on March 20.
