Terror suspect Daniel Khalife has been arrested in Chiswick, west London, and is in police custody, the Metropolitan Police said.
It comes as officers are focusing on the district after “intelligence-led activity” and confirmed sightings in the area overnight, including calls from members of the public.
The force issued a short statement which said officers apprehended the 21-year-old in the Chiswick area and he has been taken into police custody.
In their statement, the Met Police said: “We would like to thank the public and media for their support throughout our investigation to locate Khalife and we will provide a further update on his arrest in due course.”
Officers have been stopping and checking cars, inspecting car boots and asking residents for their IDs.
Armed officers and police dogs are in the area while a police boat can be seen on the River Thames close to the roads.
Khalife was believed to be wearing a black baseball cap, black T-shirt and dark-coloured bottoms, and carrying a small bag or case, the force said.
A former director general of the Prisons Service has criticised the “mess” in the system that he believes will have played a role in Daniel Khalife’s escape.
Phil Wheatley told BBC Radio 4’s Today programme: “It has highlighted that the prison system is in a degree of chaos at the moment.
“It is very difficult to make anything work well when you are just managing day by day to fumble your way through with too many prisoners and not enough staff. So, I would be surprised in the long run if that wasn’t one of the factors that led to things not working right.
“The system is just about at maximum capacity, it’s overflowing out into police cells, that’s driven by longer sentences.
“The Government has been very keen on longer sentences for criminals but they haven’t supplied the places with enough staff to supervise them, nor have they managed to maintain existing prisons.
“They’ve spent what capital they’ve got on trying to build new places, meanwhile some of the older accommodation has had to be taken out of use because it can’t be maintained – so it’s all a bit of a mess, it doesn’t look like a well-planned, thought through policy that has been resourced.”
