Police believe the bomber is the dark-clothed man in the middle
Detectives have released CCTV footage of the man they suspect planted the Ealing car bomb.
Thursday's blast - which left 11 people injured - has been blamed on dissident republican group the Real IRA.
The bomb had been left in a grey Saab packed with explosives near Ealing Broadway railway station in the bustling west London area.
The video shows a grey Saab stopping near traffic lights on The Broadway at 2300BST - an hour before the bomb exploded.
A few minutes later the man police believe is the bomber is seen walking down The Mall towards Ealing Common.
Outside a shop he appears to brush past two men who police believe may have exchanged words with him.
The other two people in the picture had just left the Royal food and wine shop.
Deputy Assistant Commissioner Alan Fry, head of the anti-terrorist branch, said: "There may have been something said between them.
"It looks like he almost bumps into someone and someone said 'look where you are going'."

Police hope the footage will jog the memory of the pair, and of anyone else in the area.
The video shows a group of eight young people walking past the car just 10 minutes before the blast, who the police say are "incredibly lucky to be alive".
Police also hope the video will jog the memory of drivers.
They say the car, which had its lights left on, was parked so close to the traffic lights on The Broadway that cars turning left had to manoeuvre round it.
The video also showed the moment of explosion just minutes after a group of pedestrians walked past.
Police say they can tell from the pictures that the man was wearing a dark short-sleeved shirt, dark trousers and a baseball cap with a white motif.
Mr Fry said: "I would not expect anyone to be able to name the bomber from what we see here.
"This is not the breakthrough that we are looking for, that's still to come."
The footage also shows the ferocity of the blast, with an orange fireball engulfing The Broadway.
A warning was telephoned to the police at 2333BST which gave police a maximum of 27 minutes to act before the explosion, said Mr Fry.
He said the information given in the phone call was misleading, and praised police for their actions.
"I think [the footage] does show from the lack of pedestrians around at the time of the explosion that efforts had been made to keep people away from that area and that was as successful as we could hope in the time available to the police."
Back to normal
On Monday residents and traders in the area were trying to get back to normal.
Some were allowed to return to their properties on Monday, but others were told they would have to stay away for some time.
The council said the section of the road where the bomb exploded would need to be closed "for the foreseeable future", although the station itself is open.
Anti-terrorist officers were still searching the area and collecting evidence, but expected to finish later on Monday.
A spokeswoman for Ealing Hospital has confirmed that a 28-year-old man, who had been treated for shoulder injuries, would be released later on Monday.
