Two people have been stabbed during an “incident” at Sony Music’s headquarters in central London.
Firearms officers and paramedics were called to the building in Derry Street, Kensington at about 11:00 GMT. An arrest was later made.
People have been evacuated from the building and roads nearby have been closed.
The Met said there was no evidence of any firearms involved and it was not being treated as terror related.
Neither of those stabbed suffered life-threatening injuries, the force confirmed.
Evacuations had taken place “as a precaution” and officers remain at the scene, they added.
