police say blew himself up at the manchester arena. his family is libyan origin. the police have arrested a 23-year-old man, it s not known what his connection with abedi is, but they are looking for family and friends to interview. they raided his house today, actually used explosives to get in to it. they are looking for computers, phones, anything that will thai him to co-conspiracy about tors. and if you remember the bataclan attack in 2015, be once police find cellphones and computers, they were able to track down the cell pretty quickly. and they are also looking at the bomb itself, almost trying to recreate it. they have been to hospital, they are coming out with evidence bags, with nuts and nails, pieces of the debris of this bomb. it was obviously quite powerful. this wasn t something that was made on a kitchen top. the question was, was it made of hydrogen peroxide, is this the work of an experienced bombmaker. was abedi the bombmaker or is
the bombmaker still loose. they will also be looking at the timing and target. yes, an measuamerican singer performing at this concert and less than three week before a british election. this could suggest some level of so sophistication. isis has claimed responsibility. police can t confirm that, but they are looking at the pieces of the jig saw that will help them find out was abedi acting alone, did he make the bomb himself, was he one of the people who came from syria and iraq. does he have co-con conspiracy abo tors, is there are a bombmaker on the streets. and this is an interesting point bill neely makes. you were part of the government task force that investigated the 2005 terror attacks in london where we were trying to figure out whether someone else made the bomb or not. what do you make of what you ve seen so far? first of all, as somebody who
the president being briefed. that s so important to understand the global connections, but really at the granular scene, we go in there and we get the guy s wallet from his blown up, bumped out pants and we pull out his driver s license. more often than not, even with terrorists, they have an i.d. on them. and that s where we start. if it s not there, finger prints are gathers, prhotographs of th remains that are left, and you are going to quickly pass that on to your intel professionals, your analysts, and they re going to start all that process that we discussed tonight. but you re then going to go to that scene, brian, the flat where this guy lives with the crucial question for the commander is, you know, is there another plot afoot? is there other people involved? and is this the bombmaker?
powerful explosive devices, also left some devices in new jersey. those devices in new york city much more powerful than the boston devices. so yeah, could be a one-man operation. but the worry is there s a bombmaker behind this, a wider cell and other parts could strike again. again, word a 23-year-old has been arrested in connection with the ongoing investigation in monday s attack in manchester. we ll see if it holds and what that connection is. clarissa, obviously we know they are throwing all terror resources at this investigation. how much concern is there about active cells or small teams working for these type of attacks with the terror alert level as high as it is there? well, the terror alert level is at severe, which basically means, chris, that another attack is likely. i think it s fair to say there s a great deal of concern that as paul said it s entirely feasible that this man may have operated
bolts, the debris that was imbedded in people s bodies trying to recreate the bomb because every piece could count. it was clearly a powerful bomb. police do not believe this was something that was made on a kitchen top. the number of casualties would suggest that this was a more sophisticated device. was it made of hydrogen per side. that is difficult to get and difficult to make. it requires some skill. it is toxic, it is dangerous. so all of these pieces of the jig saw police are working with now to try to put together a case. did this man act alone, is he part of a wired cell. did he just deliver the bomb or did he actually make it himself. if he didn t make it, the bombmaker is still on the loose here in manchester. our think thanks to bill neely. bill bratton is here, former police commission of new york city. i was thinking about the days and weeks after 9/11 when the
