The hacker group Anonymous appears to be setting its next target on the Federal Reserve, calling in a video uploaded on YouTube for Chairman Ben S. Bernanke to resign.

In the video, the hacker group said that Tuesday would be a “first step” for “public protests” until Bernanke steps down.

The hacker group has been responsible for cyberattacks that took down Web sites for the Spanish police last week and divisions of the Turkish government.

“The Federal Reserve gave trillions of American taxpayer dollars, in secrecy, to the people who were most responsible for causing our economic crisis,” the group said in the video.

It was the second call for a “nonviolent” protest of Bernanke and the Fed’s policies. The group has criticized the growing gap between the rich and poor and monetary policies that they call crimes against humanity.

The Turkish government said Monday that it had detained 32 members who are allegedly part of Anonymous. The group is described as nonviolent cyberactivists who have taken down the sites of Sony, Mastercard and Amazon.
