Terror probe arrest 'quite a scene' in west London

Four people have been arrested across London in a pre-planned terrorism operation, Scotland Yard said.

Searches are being carried out at six addresses in the capital.

A man who witnessed one of the arrests on Westbourne Grove - a street lined with restaurants and boutiques in Notting Hill - said what unfolded was "quite a scene".

The man, who did not want to give his name, said: "Well, I walked by and it seemed to be a couple of guys being arrested.

"There were three."

The man said the men "looked white" and were "up against the wall".

And there was quite a lot of police. There was quite a scene as I approached.
