The FBI says it has shut down the notorious Silk Road website - an online marketplace for drugs and illegal services.
A spokeswoman for the FBI said that the suspected operator of the site, Ross William Ulbricht, had been arrested on Tuesday.
The site was known for allowing users to buy illegal drugs and criminal activities such as "murder for hire" anonymously online.
The FBI said it has also seized approximately $3.6m (£2.2m) worth of virtual currency Bitcoin.
