David Cameron, the UK prime minister, has called for limitations on criminals using social media.
Speaking in a special debate in the houses of parliament, recalled because of this and last week's riots, Cameron said: “When people are using social media for violence we need to stop them.
“So we are working with the police, the intelligence services and industry to look at whether it would be right to stop people communicating via these websites and services when we know they are plotting violence, disorder and criminality.”
Cameron denied that government cuts would impact the number of the police on the front line, and said it would take whatever steps were necessary to ensure that the streets of cities in England were safe for people.
There have been calls in the Commons debate to censor videos which support or encourage gang violence. Cameron said that the Home Secretary would talk to Youtube and other social media to see what more could be done.
Replying to a back bencher, Cameron said that criminals were using Twitter, instant messaging and other social media to lay false trails and plant rumours.
Meanwhile, the BBC reported that police in Guernsey have arrested three people in the tiny island for misusing Facebook.
