Twitter, Facebook and Blackberry have been called to the Home Office next week to discuss the role of social media in the recent riots.
The announcement follows prime minister David Cameron's speech in the House of Commons that the government will crack down on rioters using social networks to communicate.
"Free flow of information can be used for good. But it can also be used for ill.
