The event for 700 guests in Southwark was designed to promote the virtues of the BlackBerry Messenger Service (BBM) to an invite-only list of journalists and celebrities, with a performance by Jesse J.
But a fight between two guests broke out as the singer ended her set, with one of them left in a serious condition in hospital and his accused 25-year-old assailant in police custody.
Witnesses told photographers that two men were involved in an argument as Jessie J was coming off stage, with one of them apparently plunging a broken bottle into the other man’s neck.
It is likely to be viewed as a PR disaster for BlackBerry which held the event as a mark of confidence in its troubled platform following weeks of bad news.
Industry sources have also questioned recent reports that the company is planning to pull out of the consumer market to focus solely on the business sector. They point out that the company’s handsets still have a large following among the UK’s younger smartphone users – a fact which is reinforced by Jessie J’s brand ambassadorship last night – and it is highly unlikely this lucrative market will be abandoned.
