Police are committed to "building relationships" with communities after more illegal street parties were held in London, says the Metropolitan Police.

"We're not going to arrest our way out of situations like this," Met Commander Bas Javid told BBC Breakfast.

It comes as officers broke up an event on Harrow Road, Kensal Town, on Friday night. It followed similar events in Notting Hill and Brixton on preceding nights, which saw police injured in clashes with party-goers.

"The first line is engagement and building relationships, and you don't do that by walking into every situation with riot helmets and shields," said Mr Javid.

But he stressed that "if these situations do descend into chaos and violence and disorder... we will take a much more thorough and robust position".
