LYON • International police group Interpol yesterday said nine people had been arrested in Thailand, Australia and the US, and 50 children rescued after investigators took down an online paedophilia ring.
More arrests were expected as police in nearly 60 countries pursue investigations stemming from an Interpol operation launched two years ago into a hidden "dark Web" site with 63,000 users worldwide.
Police are also trying to identify 100 more children in images that had been shared on the Internet's uncharted corners.
Operation Blackwrist began after Interpol found material that was traced back to a subscription-based site on the dark Web, where people can use encrypted software to hide behind layers of secrecy.
Such sites cannot be found through search engines, and users need to have the specific URL address to land on a site.
Interpol enlisted help from national agencies worldwide, with the US Homeland Security Investigations (HSI) department eventually tracking the site's IP address, where new photos and videos were posted weekly.
The first arrests came early last year, when the site's main administrator, Montri Salangam, was detained in Thailand, and another administrator, Ruecha Tokputza, was captured in Australia.
Salangam, whose victims included one of his nephews, was sentenced last June to 146 years in prison by Thai courts, while an associate, a teacher, got 36 years.
Tokputza was handed a 40-year prison term at his trial in Australia last Friday, the longest-ever for child sex offences in the country.
The Australian Associated Press reported that Tokputza, 31, pleaded guilty to 50 counts of abuse of 11 children - one just 15 months' old - between 2011 and 2018. "You are a child's worst nightmare, you are every parent's horror, you are a menace to the community," Judge Liesl Chapman told him.
Interpol did not identify the others arrested.
The HSI's regional attache in Bangkok, Mr Eric McLoughlin, said in a statement that "numerous arrests" had been made in the US.
Some held "positions of public trust", he said, and one was abusing his two-year-old stepbrother.
"Operation Blackwrist sends a clear message to those abusing children, producing child sexual exploitation material and sharing the images online: We see you, and you will be brought to justice," Interpol's secretary-general Juergen Stock said.
