Terror Arrests: Four Men Detained In London
Four men are in police custody after being arrested in London as part of a pre-planned anti-terror operation.
Counter-terrorism police detained the men at 7.10pm on Sunday during raids on several premises across the capital.
A statement from the Metropolitan Police said the men were arrested under the Terrorism Act 2000.
Two of the men were detained in Mansell Street, east London. A third man was arrested at a premises in Westbourne Grove, west London.
The fourth man was detained in Peckham Street, southeast London.
Officers conducted a search of six addresses as part of the pre-planned operation.
The men have been taken to a police station in south London.
Police said public safety remained their overriding concern.
A man who witnessed the arrest on Westbourne Grove - a street lined with restaurants and shops in Notting Hill - said he saw two police vans and a police car at the scene.
He said: "There was quite a lot of police. There was quite a scene as I approached."
The area was now clear, the man added.
Sky's defence correspondent Alistair Bunkall described the operation as "significant".
"Sometimes these arrests are made as a pre-emptive measure very early on in any planning for a terrorism operation, and sometimes they are made because the feeling is a terrorist attack may be imminent, but we haven't been given those sort of details yet," he said.
"But S015 officers, from Counter Terrorism Command, and armed Met Police officers were involved, so it certainly was a big operation by the Met."
