Detectives investigating the attempted bombings in London are searching a house in north west London near Paddington.

Armed police are carrying out an operation at a house in the Harrow Road area of West Kilburn, Scotland Yard has confirmed.

Sky's Correspondent Graham Leach, who is at the scene, said there is a "formidable" police presence.

He added that two women and a teenage boy have reportedly been searched by police.

The operation is reportedly centred on a Thai restaurant.

Four suspects in Thursday's attempted bombings of three London train stations and a double-decker bus have been identified through closed circuit television footage, a police source with knowledge of the investigation said.

CCTV images of the four suspects were later shown.

One commuter Teri Godly described how she had stood next to the man the British media described as a suspected suicide bomber before police charged in and shot him several times.

"A tall Asian guy, shaved head, slight beard, with a rucksack got in front of me," she told Sky News television.

More on the search:

A witness earlier said heavily armed police had descended on part of Harrow Road in west London, shouting at people to stay off the streets.

"There's what looks like a bomb disposal-type vehicle, armoured, and there's several armed officers around it," Houst Monfaradi told BBC television, adding there was a huge police presence in the area.

"About half hour an ago, police ran up my road telling everyone to get inside their houses. Anyone who even pops their head out, they scream at them: 'get inside your house'."

Looks like there is an incident in Canary Wharf. Picture and story here.
