[Whitfield:] Now for a look at this week's "CNN Hero," for than two decades Jennifer Maddox worked for Chicago's police department. Frustrated by continued violence and limited opportunities for young people, she started Future Ties, a nonprofit after-school and summer program focused on providing a free, safe space for kids to find a positive purpose.
[Jennifer Maddox, Cnn Hero:] We are in a state of emergency here in the city of Chicago. The shooting, the killing, 5, 6, 7 year-olds, they're losing people that they love and care about. I'm a law enforcement officer but I'm also a mother and a member of this community. We can't arrest our way out of this. Once, I saw that there was another side to policing. I thought that I could do more.
[Whitfield:] Well, to learn more about Jennifer, visit CNNheroes.com. And while you're there, nominate someone you believe should be a 2017 CNN hero. All right, Manchester police say they have made two more arrests linked to last week's terror bombing at a pop concert where 22 people died, a total of 13 people are now in custody. Britain's home secretary is raising concerns that some of those involved in planning the attack could still be at large. And authorities are racing to uncover the full extent of the terror network. We are also seeing newly released images of the Manchester bomber. They were taken the night of the attack on closed circuit cameras. I want to bring in CNN's Atika Shubert from Manchester. So how great of a concern is there about another potential attack?
[Atika Schubert, Cnn Senior International Correspondent:] It's a big concern, but having said that, a terror threat level has been reduced in part because police are now fairly confident that they've rounded up most of the network, or at least the first level of it. But of course, there are still the potential for others in the network to be out there. At least that's what Britain's home secretary said earlier today. I think what it really comes down to is the fact that the city realizes it has to move on despite that fear. And in fact, today people came out for the Manchester run, a half-marathon, and there were balloons, people were running, despite heavy security. Nobody here was saying that they were afraid. They really wanted to come out and show their solidarity. So I think the city wants to certainly show that it will stand up to terrorists by continuing with the normal way of life.
[Whitfield:] We're also hearing the police may have found the site where the bomb was actually assembled. What more do we know?
[Schubert:] Well, yes. This is one of the sites that we actually visited in the last few days. It's a short term rental in the city center, just about a mile and a half away from the arena. And it now looks like so it's the last place that Salman Abedi, attacker was at before he detonated those explosives. Now, what the police are looking at is whether that apartment was in fact the staging ground where he assembled that bomb. We still don't know exact details but that's what police say. They released those CCTV photos in part to get the public's help and retracing his steps over the last few days to know exactly where he was and who he was meeting with.
[Whitfield:] All right, Atika Shubert, thank you so much at the site which becomes a memorial now paying homage to 22 killed and many injured. Thank you so much. All right, thanks so much for being with me this Sunday. I'm Fredricka Whitfield. Much more in the "Newsroom" straight ahead with Ana Cabrera.
[Ana Cabrera, Cnn Newsroom Show:] You're in the "CNN newsroom." Hello on this Sunday. I'm Ana Cabrera in New York. Great to have you with us.
