Police officers revealed they have evacuated and are searching a residential address in Sunbury, Surrey.
The evacuation is a precautionary measure following the arrest of a man in Dover, Kent, at around 7.50am this morning in connection with the investigation into the terrorist attack at Parsons Green Underground Station.
Officers began evacuating the address at approximately 1.40pm today.
Residents in the buildings immediately surrounding the address are also being evacuated as a precautionary measure.
Cordons are being put in place at a 100 metre radius to facilitate the Metropolitan Police Service’s operation, which is being supported by colleagues from Surrey Police.
A search of the address is ongoing and the cordons will remain in place until the operation is complete.
Police would like to thank the local residents directly affected for their cooperation and patience. Local officers are on duty in the immediate area to talk to the community and address any concerns that they may have.
No further arrests have been made.
An armed police operation is under way in Surrey following the Parsons Green bombing.
Sources say the operation in Sunbury-on-Thames is by officers investigating the terror attack.
Officers patrolling London’s streets were joined by Met Commissioner Cressida Dick following the terrorist bombing.
The Commissioner travelled by tube to Waterloo Station and patrolled along the South Bank, as the Met’s visible presence was increased following the attack yesterday morning at Parsons Green.
She said the Force is “pleased” about the significant arrest this morning and said Londoners should remain vigilant.
“Yesterday we saw a cowardly and indiscriminate attack which could have resulted in many lives being lost. Again we saw a quick response from all the emergency services and transport staff.
“Since then, we have had teams of detectives and specialists working through the night on the investigation and officers throughout London mobilising and providing an increased visible police presence – especially in crowded places.
“Last night I visited the scene of the attack and our operations room and saw first-hand the complex and professional job carried out by our experts on the ground.
“London has not stopped after other terrible attacks and it will not stop after this one.
“Officers and staff from throughout the Met have been called in to provide extra shifts and yet again I am hugely proud of their response. We are pleased that there has been a significant arrest this morning but the investigation continues and updates on this will be provided as we are able to.
“I have joined officers out in central London today, meeting Londoners and visitors. It is a simple message, but a powerful one, to see London getting on with its business enjoying the weekend and everything the city has to offer.
“You can help us by remaining vigilant and letting us know if you have any concerns.”
Both armed police and soldiers are on duty in Whitehall.
And armed police were even seen at a Food Festival in Liverpool
Security minister Ben Wallace suggested CCTV images of the bomber could be released as part of the manhunt for those responsible, but Scotland Yard subsequently denied there were any plans to do so.
Tech giants “can do more” to tackle extremism online following the Parsons Green bombing, the Security Minister has said.
Concerns over the availability of terrorist and bomb-making material on the internet have been reignited after the UK was targeted by its fifth terror attack of the year.
MP Ben Wallace said the Government would continue to “put pressure” on companies to invest in technology which could quicken the take down of terrorist material. Mr Wallace told Sky News:
“We are constantly trying to build that pressure, explaining to them that we think that they can do more and where we need to, we get tougher on them.
“They cannot be removed from some of the responsibility they carry and we think there is technology out there that could make these take downs quicker.”
He added: “It is a 21st century phenomena. We have to deal with it. On the internet people can learn how to make bombs, they can learn how to use weapons.”
Detectives investigating the terrorist attack have made an arrest in connection with the investigation.
An 18-year-old man was arrested by Kent Police in the port area of Dover this morning, Saturday, (September 16), under section 41 of the Terrorism Act.
The man remains in custody at a local police station. He will be transferred to a south London police station in due course.
Deputy Assistant Commissioner Neil Basu, Senior National Co-ordinator for Counter Terrorism Policing, said:
“We have made a significant arrest in our investigation this morning. Although we are pleased with the progress made, this investigation continues and the threat level remains at critical.
“The public should remain vigilant as our staff, officers and partners continue to work through this complex investigation. We are not, at this time, changing our protective security measures and the steps taken to free up extra armed officers remain in place.
“This arrest will lead to more activity from our officers. For strong investigative reasons we will not give any more details on the man we arrested at this stage.”
Detectives from the Met’s Counter Terrorism Command are continuing to urge anyone with information about the terrorist attack to contact police.
British Transport Police will also have more officers than usual patrolling at stations, as well as on trains across the country.
Assistant Chief Constable Alun Thomas, head of Specialist Operations at BTP, said:
“Now that the threat level has increased, we will be deploying a number of additional officers throughout the national rail network.
“Our officers have been given specialist training in counter terrorism policing – including behavioural awareness skills.
“This means that their day-to-day policing role is keenly focused on keeping passengers and staff as safe as possible.
“Over the coming days, we’ll be keeping a close eye to keep you safe, as well as making sure the nation’s railways keep functioning as usual.
“Everyone should remain calm, but vigilant. Rail passengers and staff are the eyes and ears of the network and we want to hear from you if you see something that doesn’t look right.
“Nothing should be considered too small or insignificant, it may be vitally important to us.
“Throughout England, Scotland and Wales, my officers will be highly visible and there to reassure you as you go about your weekend.”

I normally get the train around that time depending on if I’m early or running late.
It feels horrible to even think about being in the same train and I don’t even want to think about what would of happened if I was near it but it’s something that you don’t expect to happen to you.
Luckily I was one of the lucky ones
