WASHINGTON, Oct 26 (Reuters) - An international operation targeting trafficking in opioids on a clandestine part of the internet called the darknet market has led to about 150 arrests in the United States and Europe and the seizure of drugs, cash and guns, U.S.

and European authorities said on Tuesday.

German police have taken down one of the world's largest child porn dark web sites with over 400,000 members and arrested four people accused of running it.

The site, known as BOYSTOWN and accessible only via the so-called Darkweb, had existed since July 2019 and was used for the worldwide exchange of child porn.

The self-proclaimed 'Crocodile of Wall Street' and her husband have been granted bail set at $3million and $5million respectively after being arrested for allegedly laundering $4.5billion in Bitcoin stolen in the 2016 Bitfinex exchange hack. 

Police around the world have arrested 150 suspects in one of the largest-ever dark web sting operations.

The suspects arrested included several high-profile targets, involved in buying or selling illegal goods online, Europol said today.

Operation Dark HunTOR also recovered millions of pounds in cash and bitcoin, as well as drugs and guns.
