A man has been charged over the murder of a father of two who died following a bottle attack at a star-studded party, police have said.
Brit Award-winner Jessie J performed at the function hosted by smartphone company BlackBerry before Phillip Sherriff was fatally wounded.
The married 37-year-old telecommunications professional, who was employed by the technology firm, died in hospital on April 8 after a four-day battle to save his life.
A Metropolitan Police spokesman said company director Ashley Charles, 25, has been charged with murder.
Charles, of Nevanthon Road, Leicester, appeared in court on April 7 charged with attempted murder. He will now appear in custody at Bromley Magistrates' Court on April 25 to face a murder charge.
Jessie J said she was "lost for words" after the attack at Pulse nightclub in Southwark, central London.
In a Twitter posting, the chart star wrote: "I am lost for words. All I can say is my thoughts, love and respects are with the family and children of the man who attended the blackberry gig last week who sadly lost his life this morning... So sad."
Mr Sherriff, from Preston, Lancashire, was rushed to the Royal London Hospital after suffering a neck injury. Medics were later forced to operate on his skull to remove pressure from an injury to his brain.
BlackBerry posted a message of condolence on its official UK Twitter page following the news.
It said: "We are deeply saddened to hear our colleague has died as a result of the attack on Tuesday 3rd April. Our thoughts are with his family and those close to him and we ask for the respect of their privacy at this difficult time."
