WikiLeaks founder and editor-in-chief Julian Assange was arrested on charges of sexual assault this morning, after voluntarily going to a police station in central London.
A European arrest warrant was issued by the Swedish authorities last night, and Assange is due to appear in City of Westminster magistrates' court within the next few hours, according to Sky News.
Assange is accused of sexually assaulting two women when he visited Sweden in August, which he denies.
The allegations have been labelled a "political stunt" by Assange's solicitor Mark Stephens, who said that any attempts to extradite his client will be resisted on the ground that he may be handed over to the Americans.
WikiLeaks has been under intense pressure in the past week and faced two distributed denial-of-service (DDoS) attacks after publishing a huge set of confidential US government cables.
Companies providing services to WikiLeaks have withdrawn support, most prominently Amazon Web Services, which removed the site from its servers last week.
PayPal, meanwhile, has permanently restricted the WikiLeaks account, accusing the site of violating its Acceptable Use Policy which states that customers may not encourage, promote, facilitate or instruct others to engage in illegal activity.
MasterCard confirmed is the latest organisation to withdraw services from WikiLeaks.
"[We are] currently in the process of working to suspend the acceptance of MasterCard cards on WikiLeaks until the situation is resolved," the firm said in a statement to V3.co.uk.
