A BRITISH-AUSTRALIAN dual national living in Dubai who wanted to raise money for Afghans who fled their country’s long war has been detained for weeks over promoting a charity, his supporters said.

Scott Richards’ case appears to be the first prosecuted under a new law that regulates charities amid regional concerns about cash donations reaching extremists.

However, his supporters warn the regulations can be applied to anyone wanting to do good by donating to international causes or even talking about them online.

“I’m shocked and horrified. It’s heartbreaking because you’re trying to do something so simple to make a positive difference just to help,” said Mr Richards’ brother, Brett.

“Relieving suffering was the only goal Scott had.”

Mr Richards, who grew up near Adelaide, and is married with two children, remains held at a Dubai police station. He appeared at a brief hearing on Thursday.

He was arrested July 28, apparently over his support of the Zwan Family Charity in Afghanistan after advising the local government there, his brother said.

Since the US-led invasion of Afghanistan following the September 11, 2001, terror attacks, a number of small charities have set up in Kabul to aid those maimed or left homeless by the country’s decades of war.

Zwan Family Charity, registered as a public charity in Richmond, Texas, with the US Internal Revenue Service, joined them relatively recently, in 2013.

One of its projects focuses on providing tarps to protect against the elements for those living in Charahi Qambar, a community of mud homes northwest of the Afghan capital, Kabul.

Mr Richards was a friend of a friend to the organisation and put out a statement supporting it and urged people online to donate to the tarp project, said Kimberly Wolenski, the vice president of Zwan Family Charity. She stressed the non-profit has full accounts of its finances, urges its donors to follow local laws and has no ties to political or militant groups in Afghanistan.

For Mr Richards, his trouble apparently began after posting online about the charity and being quoted in a local Dubai newspaper about its efforts.

“I think he was trying to raise awareness about the situation in Afghanistan,” his brother said. “He was just shocked when he saw the conditions. I think he just thought, ‘Maybe I can do something’.”

Under a decree last year by Dubai’s ruler, Sheikh Mohammed bin Zayed Al Nahyan, the emirate banned raising money or promoting any charity online or through the media without first getting the approval of the city-state’s Islamic Affairs and Charitable Activities Department.

The decree, which exempted ruling family members, set penalties of up to one year in prison or a 100,000-dirham ($35,000) fine for violators.

The Dubai Media Office did not respond to a request for comment on Mr Richards’ case.
