Police believe he stayed there as recently as 7pm on monday evening of the night of the attack. Todays operation involved armed units, some wearing military clothing. Got to the front door and was greeted by an armed Police Officer with a helmet, face mask machine gun. I asked him what was happening. Hejust said operations, out to gain access to the apartments, they blew down a door. Other police units arrived looking for any signs of a bomb factory. There have been raids in different parts of the city, this one involving armed units. The police regard themselves as in a race against time, trying to find other members of the network to prevent further attacks. This was just one of a number of Police Operations carried out in manchester today. Youll be aware that the level of activity in this investigation is intense and is continuing at a fast pace. I think its very clear that this is a network that we are investigating. As i said, it continues at a pace. Late afternoon and a new arrest, this time on the street in wigan. A man detained. Police say he was carrying a suspicious package. The uk is now a country on high alert. This was reading this morning. And this was the Scottish Parliament in edinburgh.

Operation temperer has now been invoked, and that means there will be additional Military Personnel coming to backfill the armed Police Officers so that they can support other areas. All of the Special Operations are aimed at discovering the circle linked to salman abedi, the manchester bomber. It has become clear that he was part of a terror cell.

Its like its happened to someone in your own family. Ijust its happened to someone in your own family. I just wanted its happened to someone in your own family. Ijust wanted to come. I brought a red, white and blue rose down and just wrote some words and just felt like i had to come. Tonight, manchester is a city that knows there may be people in its midst who planned mass murder and may strike again. Gavin hewitt, bbc news, manchester. This evening The Independent is reporting that police have found more explosives which could be primed for and in and attack. An Doan Thi Huong the line now by the defence responded for The Independent for an imminent attack im joined. You wrote this story on The Front Page of The Independent. Tell us more. We have been told that the police have found material that can be turned into explosive devices as part of the searches. They found one device which was blown up in a controlled explosion. There is no suggestion that bombs are in place to go off. But what i was told was that they had found material which was worrying in pattern with what they thought theyd find. Are you able to say where this material was found . dont know is the answer. What i do know is i cant be sure. I was told that there was one particular device which was blown up. And the others we re which was blown up. And the others were not completed devices. Are you able to say where this material was found . Again, knowl cant. What does this suggest to you . found . Again, knowl cant. What does this suggest to you . I think it is in line with what the police are saying, that this is a very serious matter. As you know they have carried out six arrests so far. They have done operations in libya as well and an ongoing threat. The severity of it of course is something we are not sure about. To a certain extent i think we are. It seems to me from what we know, this is something obviously they are taking very seriously and it is something they are finding evidence to support them taking this seriously. The story that you have written, are your sources uk sources . Not entirely. Im sorry, can you repeat that . It wasnt entirely all uk sources. There was one which was not a uk source. Do i ta ke one which was not a uk source. Do i take that to mean that was an american source . I really dont want to go into where that came from. Can you tell me anything more about the device that was blown up in the controlled explosion . You say that this wasnt the sort of bomb you would think of as such but something that might have been used in bomb making . That might have been used in bombmaking . It was something they felt which was dangerous. Material which could have been used to inflict damage and the decision was taken to carry out a controlled explosion. More than that im afraid i wasnt told. Do you get the impression from whoever it is youve been speaking to that they expect to find more of this sort of material . Certainly they are on the lookout for it. The impression i got was that they are finding things as they carry out arrests and searches. The impression i get is they are finding more and more leads to go through and to follow up. But the precise extent of what theyve got, i do not know. All i do know is basically what i have told you. Kim sengupta, from The Independent, many thanks for joining from The Independent, many thanks forjoining us this evening. Our middle east correspondent Quentin Somerville is in libya, where one of The Brothers Of Salman Abedi was arrested today. He was asked about the likelihood of abedi becoming radicalised while on a visit to libya. We heard this evening from the militia which detained hashim, the younger brother, and ramadan, the father, that hashim was in contact with his younger brother, sal man, and funds were transferred between them and hashim was planning an attack in tripoli, they are holding him in beliefs they have links to the Islamic State. Thejourney him in beliefs they have links to the Islamic State. The Journey Sal Man took here was a regular trip. His parents man took here was a regular trip. H is pa rents left man took here was a regular trip. His parents left libya as part of an exodus during gaddafis time. Gaddafi said extremists were fleeing here. But that isnt the whole story because there was another exodus that happen here in libya after 2011 when Moammar Gaddafi was ousted and that exodus was thousands of libyan fighters heading towards syria. Theyve taken the skills they learned in the Battle Against Gaddafi and they honed them further in syria. Then they returned here to libya with those sharpen skills and they set up a base for the Islamic State in syria inside this country. Hugh, its worth remembering, western governments do not have a presence inside libya, they closed all of their embassies, that makes it much more difficult for western intelligence agencies to have a presence here and to gather every information on the likes of the abedis and others who may have linked to Extremist Groups here in libya, in syria, in iraq and in europe. Quentin somerville there. Reports have emerged there were warnings given to the authorities may be five yea rs given to the authorities may be five years ago about abedis comments and thoughts. Al security correspondent Gordon Corera was at the m15 headquarters in central london. At mis at m15 they are prepared for some tough questions about what they knew and when about abedi. They knew he was known to the authorities this morning, thats what the Home Secretary said, but this morning we learned much more about the number of people raising concerns about Extremist Behaviour and that being flagged to the authorities. That would have meant a Risk Assessment would have meant a Risk Assessment would have meant a Risk Assessment would have been done and there will be questions about whether anything was missed, anything significant. Here at m15 they are stressing that their priority is the current ongoing and urgent operation into him, into that network, trying to establish particularly who made that bomb, because they look like sophisticated devices from the picture. Sophisticated device from the picture that was leaked to the New York Times, thats raised concerns about who the bomb maker might have been, assuming it wasnt salam abedi. I understand there are concerns about what are called unaccounted materials, these may be precursors, chemicals used to make the bomb, and there may be more out there that were purchased or gotten hold of that were used in this device and that may be one of the reasons the threat level has gone up to critical. Greater manchester met said he was troubled by the pictures published. He said he raised complaints with the american ambassador. On monday evening the reports were coming through and i agreed with the cheap Co Mforta Ble through and i agreed with the cheap comfortable that we should take a cautious approach to put information out because we would not want to get anything wrong or compromise police investigations. Yet the first reports were coming out of the United States and that is concerning. Obviously, you want International Cooperation because events like these can have a broader dimension but it worries me greatly andi dimension but it worries me greatly and i have made my concerns clear to the ambassador.
