Manchester investigation at 'full tilt' - another arrested today

Manchester-born Abedi, of Libyan origin, injured more than 100 people when he detonated his explosive as concertgoers left a show by USA teen idol Ariana Grande.

The huge police operation that followed saw raids in several cities as counter-terror efforts were focused on cornering his suspected criminal ring.

Home Secretary Amber Rudd warned Sunday on BBC that members of the network behind the attack by the deceased Abedi remain "potentially" unaccounted for, but "the operation is still really at full tilt in a way".

British police today conducted fresh raids in Manchester and arrested a 19-year-old man in connection with the concert bombing, taking the total number of those in custody over the attack to 13. Another brother and Abedi's father have been detained in Libya.

Abedi reportedly returned from Libya only a few days before the attack which killed 22 people, including seven children under 18, but police are still trying to establish the extent of his wider network.

Additional security measures were in place for the Great Manchester Run on Sunday, which attracted tens of thousands of participants.

Investigators say they have a 1,000-strong team working "around the clock" on the probe and have significant details on Abedi's associates and movements, his finances, and how the explosive was built.

MI5 has launched a "post incident investigation" into how the Manchester bomber was overlooked, while a separate report is being prepared for ministers and those who oversee the work of the service.

"But I would not rush to conclusions, as you seem to be, that they have somehow missed something".

The hunt continues for suspected less-important conspirators as soldiers deployed on the streets prepare to return to barracks after the UK's terror threat level was reduced from critical to severe.

Now government sources have told sections of the United Kingdom media that they believe 23,000 people with extremist tendencies are living in the UK.

Her mother Marie said after the bombing, Millie was wondering if the pop singer was alright and wanted people "more injured than her" to go on stage.
