British police has vowed to track down and arrest protesters who posted "inflammatory" and "inaccurate" messages on BlackBerry Messenger service, Twitter and Facebook during three days of rioting in London.
For looters and rioters the communication tool of choice has apparently been BlackBerry Messenger (BBM) which acted as their private, encrypted social network for rallying around potential targets.
The Scotland Yard said it is tracking down the persons who posted "really inflammatory and inaccurate" messages on social media, that was used to organise and coordinate the riots in London.
BBM, as it is known is an instant messaging application, allows users to communicate in a similar way as text messaging, but effectively without charge, as traffic is exchanged via the Internet.
Research in Motion, maker of the BlackBerry, in a statement said it would cooperate with a police investigation into claims that its popular messenger service played a key role in organising the riots.
Although Twitter and Facebook have played a key role in past unrest in the capital, the Tottenham riots are thought to be the first in the UK so heavily orchestrated using BlackBerry Messenger.
