Three firearms were also found by the authorities on Monday; two were found at the funfair itself, and the third was found during a traffic stop in Harrow involving individuals who were presumably on their way to the event.
This weekend's two-day celebration of Caribbean culture, which its organisers dubbed "the greatest community-led event on the planet," was projected to draw in almost a million attendees.

He said the "vast majority" of people attend the event to have a good time, but Sunday had been "marred by unacceptable violence".
