'Hackers' held in US and Europe

19 July 2011 Last updated at 23:18 GMT Anonymous rose to fame attacking the Church of Scientology and Kiss bassist Gene Simmons Police in the US, Britain and the Netherlands have detained more than 20 people as part of an investigation into major cyber attacks.

Most of the arrests were in the US, where the FBI said 16 people had been held for alleged computer hacking.

Fourteen of them were suspected of an online attack on PayPal, claimed by hacking group Anonymous, said the FBI.

In Britain, a teenager was arrested in London, while four other suspects were detained by police in the Netherlands.

Wikileaks 'revenge'

The US indictment against 14 of those arrested on suspicion of December's attack on PayPal said it had been "retribution" for the site closing a donation account for the whistleblowing website Wikileaks.

The PayPal attack suspects were arrested in Alabama, Arizona, California, Colorado, Washington DC, Florida, Massachusetts, Nevada, New Mexico and Ohio, US officials said in a statement.

Investigators believe Anonymous is mostly made up of hackers in their teens and early 20s

The other two US suspects were held under separate indictments but similar charges in Florida and New Jersey.

In the UK, Scotland Yard told the BBC that it had arrested a 16-year-old boy in south London on suspicion of breaching the Computer Misuse Act 1990.

"The Metropolitan Police is liaising with the FBI and indeed with our Dutch colleagues," a Scotland Yard spokesman said.

As well as attacking PayPal, Anonymous also temporarily shut down MasterCard and Visa last December, after they froze Wikileaks accounts.

Anonymous targeted Amazon, too, after it removed Wikileaks content from one of its servers, but that attack was not successful.

The hacking group has used a technique known as a distributed denial of service (DDoS) in an attempt to take the sites offline.

DDoS attacks bombard a website with data until it cannot respond, rendering it inaccessible.

Anonymous rose to fame with a series of attacks on websites linked to the Church of Scientology and Gene Simmons, bassist with the rock group Kiss.
