Gregory David Roberts - "In July 1980, Roberts escaped from Victoria’s maximum security prison in broad daylight to become one of Australia’s most wanted men.[3] He later claimed that he had been tortured while in solitary confinement, and that this was the main reason for planning an escape. After briefly going to New Zealand, he lived in Mumbai, where he became involved with the local mafia, and lived there for 10 years. Roberts was attracted to Mumbai because of its remarkable energy, the freedom of its people and their ability to overcome poverty. During his stay in Mumbai, Roberts was thrown into Arthur Road jail and tortured there as well, by being tied up, hung upside down and beaten with sticks. He was released from the jail some time later due to bribes paid by a senior member of the Indian mafia. Roberts ended up working for the mafia, smuggling drugs and passports. He also went to war in Afghanistan to fight with the mujahedin."
He wrote a book called Shantaram which outlines a lot of the stuff he did after his escape...pretty insane read.
