Armed British police searched a home Saturday in a London suburb of Sunbury. Authorities said an 18-year-old man was arrested in a port area of Dover. A police statement called that arrest "significant."

London Police Commissioner Cressida Dick told reporters Saturday that the threat level has been altered.

"We have a very considerable threat. My colleagues in the intelligence agency would say that this is a shift in threat, it's not a spike."

Earlier Saturday, London Transit authorities said they had reopened the Parsons Green station where the bomb on a train partially detonated.

The protesters marched past the U.S. Embassy on their way to the main offices of extreme-right, anti-immigrant Golden Dawn party, demanding that the offices shut down and party members jailed.

Police wouldn't let the march reach the Golden Dawn headquarters and had some firebombs thrown at them. Police responded with tear gas.

The marchers have mostly dispersed, but a small group did throw fire bombs outside police headquarters and three have been detained.
