WA Police are responding to a threat made against the Survival Day / Invasion Day rally in Boorloo/Perth.
A witness at the rally advised National Indigenous Times she'd been told a device had been found.
Move on orders were issued, the witness said, and police began using megaphones to tell the crowd to disperse, warning "there is something in the crowd that poses a risk your safety".
Just after 1pm Monday, WA Police said in a statement they "are currently responding to reports of a threat in Forrest Place in Perth CBD".
"Significant police resources have been deployed to the area, and an exclusion zone has been established," they said.
"Members of the public are asked to stay away from the area and await further advice.
"One person is in custody and assisting police with inquiries. We will provide more information as soon as possible."
Later, it emerged that a man had allegedly thrown a homemade bomb had been thrown towards the stage from above - which did not explode.
More to come.
