Dutchman Rop Gonggrijp, one of the founders of the internet service provider XS4all, is under investigation in the US for his role in supporting the whistleblowers website Wikileaks, the Telegraaf reports.

The US justice authorities have ordered the microblogging site Twitter to provide it with Gonggrijp’s personal details, including IP address, Twitter accounts, bank details and phone numbers.
Gonggrijp is one of five people the document names. The others are Wikileaks founder Julian Assange, US solder Bradley Manning, Icelandic MP Birgitta Jónsdóttir and hacker Jacob Appelbaum.
Gonggrijp, whom the paper describes as a ‘master hacker’ was also involved in trying to get Dutch webhosting companies to host Wikileaks on a €1m contract, the Telegraaf says a Dutch source has told the US justice department.

On his personal website, Gonggrijp says he is talking to lawyers to try and understand exactly what is going on.
He suspects the move is in connection with a Wikileaks video released in April 2010 which shows a Reuters photographer being shot from a US helicopter in Baghdad, followed by the shooting of civilians trying to rescue him.
The preparations for spreading the video were made in Iceland.
