Four people have been arrested in Spain though to be alleged "hacktivists" from the Anonymous group.

The information was reported by the European Police Office Europol.

Europol had coordinated the joint operation with the Spanish police.

The operation, codenamed Thunder, was the result of an 8-month-long investigation against a group of hackers, believed to be responsible for attacks on sites and servers and for releasing on the internet personal data of Spanish police officers.

Japan's top weapons maker has confirmed it was the victim of a cyber attack reportedly targeting data on missiles, submarines and nuclear power plants.

Mitsubishi Heavy Industries (MHI) said viruses were found on more than 80 of its servers and computers last month.
The government said it was not aware of any leak of sensitive information.

But the defence ministry has demanded MHI carry out a full investigation. Officials were angered after learning of the breach from local media reports.
