Commander Dean Haydon, head of the Met Counter Terrorism Command, said:
"This continues to be a fast-moving investigation. A significant amount of activity has taken place since the attack on Friday.
"We now have six males in custody and searches are continuing at five addresses. Detectives are carrying out extensive inquiries to determine the full facts behind the attack.
"We anticipate that the searches will take some days to complete and may cause further disruption. However, it is important that we continue with these searches and I'd like to thank all those affected for their support, patience and cooperation.
"As police and our partners do all we can to confront the threat, public vigilance remains as vital as ever.
"We urge the public to report any suspicious activity to the police by calling us, in confidence, on 0800 789 321, or in an emergency by dialling 999.
"We are asking the public to look out for anything that seems out of place, unusual or just doesn't seem to fit in with day-to-day life. It may be nothing, but if you see or hear anything that could be terrorist-related, trust your instincts, then act, and call us."
- The arrests in Newport were carried out by officers from the Met's Counter Terrorism Command, supported by colleagues from Gwent Police and the Welsh Extremism and Counter Terrorism Unit (WECTU). Searches at the two addresses in Newport are ongoing.
- Searches at two addresses in Surrey are still ongoing and are expected to last some days. The search of an address in Thornton Heath has commenced. The search at a commercial property in Hounslow has now concluded.
We would like to thank the public for their patience and cooperation.
