 On 24 April 1834, Calyute led a raid of 20 to 30 men and women on Shenton's Mill, in South Perth, where they stole half a ton of flour.It is speculated that the increased tensions were related to a dispute a few months before between the Pindjarup people and Noongars of the Swan River area.Loss of the white settlers' livestock by the aborigines' dogs, and the killing of kangaroo by settlers may have also raised tensions between the groups.
