London ( CNN ) -- British Home Secretary Theresa May sat down with officials from the social media industry Thursday , her office said , as the government considers trying to ban people from social networking during or after crises . But the government `` did not seek any additional powers to close down social media networks , '' the Home Office said . Twitter , Facebook , and BlackBerry maker Research in Motion all declined to say beforehand what position they would take at the meeting . Top police officers and other government officials were also present for the meeting , which follows riots that swept England earlier this month . Prime Minister David Cameron suggested limits on social networking in the wake of the unrest . He told Parliament August 11 that `` when people are using social media for violence , we need to stop them . '' Thursday 's meeting was about `` whether and how we should be able to stop people communicating via these websites and services when we know they are plotting violence , disorder and criminality , '' the Home Office said in a statement prior to the discussion . `` Social networking is not a cause of the recent disturbances but a means of enabling criminals to communicate , '' it said . `` We are working with the police to see what action can be taken to prevent access to those services by customers identified as perpetrators of disorder or other criminal action , '' the ministry said . Police and politicians have pointed to social networking sites , such as Twitter and Facebook , as well as mobile messaging services like BlackBerry 's , as tools used to organize looting and violence . Two men have been sent to prison for posts on Facebook urging people to riot in northwest England . Cheshire Police named them as Jordan Blackshaw , 20 , and Perry Sutcliffe-Keenan , 22 , when they were sentenced last week . Neither of their Facebook posts resulted in any rioting , a Cheshire Police spokeswoman said . In handing down the sentence at Chester Crown Court , Judge Elgan Edwards said he hoped the sentence would serve as a deterrent to others . Cheshire Police Assistant Chief Constable Phil Thompson said `` technology was used to spread incitement and bring people together to commit acts of criminality , '' making it `` easy to understand the four-year sentences that were handed down in court . '' The unrest , which was sparked by the shooting of a man in London August 6 , led to widespread looting and damage . Five deaths have been linked to the violence . The Association of Chief Police Offices sent a representative to Thursday 's meeting , it confirmed , but declined to give any other details , saying it was a private meeting . The group has not taken a position on whether people should be barred from social networking . London 's Metropolitan Police also declined to say what its position would be at the meeting . CNN 's Andrew Carey and David Wilkinson contributed to this report .
