This news recently hit the main steam that Spanish Police captures 4 members of leader-less cyber Activist Anonymous. These claimed to be hackers were caught in Madrid and Malaga. They were charged with hacking websites of Political parties, police and companies.
For Example  'Union Progress and Democracy' party (UpyD) was hacked and Pictures of Vampire were uploaded!
Spanish Police said they are working to uncover other people and more arrests could take place in next few days. Police also seized some 25 computers and other objects that might convict the Hackers.


RESPONSE:
=========
Anonymous response was strong and they made is clear "THESE PEOPLE ARE INNOCENT AND NOT THEIR PART" . InterPol however announced that all the operation was conducted under the umbrella of Operation Unmask. So lets see what will happen in future and how these arrests could have an effect on the internet users and members of Anonymous.
