A third suspect has been arrested in connection with the ‘bucket bomb’ that ripped through an Underground train at Parsons Green.
A 25-year-old man has been detained in Newport, Wales, in connection with the terror attack, Scotland Yard said.
Syrian refugee Yahya Faroukh, 21, and an 18-year-old believed to be from Iraq, remain in police custody.

Officers from the Met’s Counter Terror squad swooped on the man just after 7pm this evening, with assistance from local forces.
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 three men in custody and searches are continuing at four 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.’
He added: ‘As police and our partners do all we can to confront the threat, public vigilance remains as vital as ever.
‘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.’
Faroukh is being quizzed in a south London police station after he was arrested just before midnight on Saturday outside Aladdin’s Fried Chicken, in Hounslow, where he worked.
This followed the arrest of the 18-year-old at the Port of Dover at around 8am that morning.
