We sincerely hope that everyone is OK and that the crowd at the event stays calm as the police do their job. As of now, there is no official word from BlackBerry on what has happened or how it will handle the event moving forward.
UPDATE: According to a reporter at the Daily Telegraph, the police department have made one arrest:
Met: Man in serious condition in hospital after incident shortly after midnight at #bbmparty in SE1. One arrest. Guests still held.
