THAILAND: A 93-year-old Australian man accused of raping four young Thai sisters in one of the worst child sex abuse cases investigated in Thailand is likely never to face justice.

Karl Joseph Kraus, a former railway worker from Sydney, wants a court to drop the charges because he says he is suffering from terminal prostate cancer.

“I’ll be dead,” Mr Kraus told Fairfax Media from a court cell in the northern Thai city of Chiang Mai.

“Nobody helps me. This is terrible … they put me in jail when I was sick,” he said.
