On 17 April 2005, nine young Australians were arrested in Bali on charges of trafficking heroin. Four of the group —Renae Lawrence, Martin Stephens, Scott Rush and Michael Czugaj — were caught with the drugs taped to their body. Two others, Andrew Chan and Myuran Sukumaran, were alleged to be the ringleaders of the well-organised operation. And a final three — Si Yi Chen, Tan Duc Thanh Nguyen and Matthew Norman — were also scooped up as the final element in the Bali Nine, as the group came to be known.
