Two kitchen staff have been stabbed at Sony Music's London headquarters.
Sony issued a statement confirming the building was evacuated after two members of the catering staff were involved in a violent altercation.
A London Ambulance Service spokeswoman said one patient was taken to hospital, the other to a major trauma centre. Neither are believed to have life-threatening injuries.
"Two members of the catering team were involved in a violent altercation," a Sony Music spokesperson said. "The incident is now in the hands of the Metropolitan Police."
A witness told the Daily Mail the pair involved were "slashing each other up" with seven-inch knives. Others said they hid under tables as the fight went on.
One person was arrested.
