The Justice Department announced Wednesday the largest-ever U.S. seizure of cryptocurrency linked to so-called “pig butchering” scams that have cost victims billions globally.

Federal prosecutors filed a civil forfeiture action targeting more than $225 million in cryptocurrency traced to a sprawling web of fraudulent investment platforms. Victims were tricked into believing they were investing in legitimate crypto ventures, only to be scammed by criminal networks often operating overseas.

“This seizure of $225.3 million in funds linked to cryptocurrency investment scams marks the largest cryptocurrency seizure in U.S. Secret Service history,” said Shawn Bradstreet, special agent in charge of the U.S. Secret Service’s San Francisco Field Office, in a statement.

Authorities said the network was connected to at least 400 suspected victims worldwide, including dozens in the U.S. Crypto fraud was responsible for more than $5.8 billion in reported losses last year, according to FBI data.

The seized funds are now subject to forfeiture proceedings aimed at eventually returning money to victims.

The U.S. Secret Service and FBI used blockchain analysis and other tools to trace the cryptocurrency back to stolen assets. The DOJ credited Tether, the world’s largest stablecoin issuer, for assisting in the operation.

According to the complaint, the funds were linked to the theft and laundering of money from victims of cryptocurrency investment fraud schemes, commonly known as confidence scams that often involve romance.

The network relied on hundreds of thousands of transactions to obscure the origin of the funds, using sophisticated blockchain maneuvers to conceal the flow of stolen assets.

Kim Kardashian fans are going to have to wait a little longer for the highly anticipated NikeSKIMS line.

The activewear line will launch later this year instead of in the spring, like the companies had originally announced, because of production delays, according to a person familiar with the matter who requested anonymity to speak candidly. The person added that the delays are internal and not because of a supplier or shipping issue.

No date has been determined for the new launch date, the person added.

The person also said the relationship with Kardashian and the brand is still strong and that everyone is on the same page, but they want to make sure they take their time and get the products right.

Nike first announced the Skims partnership in February and said it would include apparel, footwear and accessories. Since then, Heidi O’Neill, one of the key leaders behind the partnership, has left the company.

New Nike CEO Elliott Hill has been betting big on the Skims brand as he looks to re-invigorate the company after recent declines in sales and its business. For Skims, which was last valued at $4 billion, the partnership with Nike brings a growth opportunity as it expands into athleisure.

Nike’s stock is down more than 20% year-to-date.

“The origin of NikeSKIMS is rooted in a desire to bring something new and unexpected to an industry that is craving something different, and to invite a new generation of women into fitness with disruptive product designed to meet their needs in both performance and style,” the company said about the line when they introduced it.

The news was first reported by Bloomberg.
