It is one of the most bizarre crimes of our times. Con men posing as police officers are forcing Chinese students to fake their own kidnapping. Elaine Chong reports on the extremes to which criminals will go to make money from their victims. The scammers trick Chinese people studying abroad into believing that they are wanted for crimes back in their homeland, and that they must hand over large sums of money to avoid repercussions for them or their family. When the students can no longer meet the escalating demands they are told to fake their own kidnapping so the fake police can seek a ransom from their relatives back in China.

Wendy Sharpe is an multi-award winning Australian artist working on a new exhibition Spellbound for the Art Gallery of New South Wales in Sydney.

Regina Botros joins her as she works towards this immersive, labyrinth-like exhibition, where the lines between art and artist are blurred.

The government’s answer was a plan to raise taxes, in what was called the Finance Bill, and this created a spark for protests across the country. According to estimates by the state-funded rights commission, 39 people have been killed in those demonstrations. Parliament was set on fire and hundreds were arrested. Many of those protesters are in their 20s, from what is known as Generation Z. Ultimately, President Ruto said he would not go ahead with tax increases, and he would listen to the country’s youth - but the protests continue.

In many countries around the world, trying to take your own life is still a criminal offence. People who have attempted suicide are often put in prison and deep-rooted religious beliefs and cultural attitudes are often behind the criminalisation laws.

Ashley (whose partner tried to take his own life twice) also speaks to mental health specialists in countries which have recently changed the law like Singapore and Pakistan. He hears how despite decriminalisation stigma around suicide prevails.
