United Kingdom police arrest 15th person in connection with Manchester attack

LONDON (AP) - British police made two more arrests and stormed three more locations Sunday as they hunted for suspects in the Manchester bombing, while a government minister said members of attacker Salman Abedi's network may still be at large.

The police statement said one of the last places he went to before the attack at the Manchester Arena venue was a city centre flat, where they believe he may have finished assembling the device. Following the attack, terror threat level was raised to critical. "The country should remain vigilant". The troops will gradually be withdrawn from Monday, May said.

In the latest police action on Saturday, officers used a controlled explosion to gain entry to an address in the north of the city where two men were detained.

Abedi was known to United Kingdom security services, but his risk to the public remained "subject to review", according to reports.

Rowley said the investigation had made "rapid progress", and police "are getting a greater understanding of the preparation of the bomb". "There will be more arrests". Police have 11 suspects in custody including Abedi's elder brother Ismail - and have searched properties across the northwest England city.

"From the day we started putting the Dangerous Woman Tour together, I said that this show, more than anything else, was meant to be a safe space for my fans", the 23-year-old added.

Armed police officers and soldiers were deployed at soccer matches, concerts and other big events.

The Times newspaper said on Saturday that intelligence officers had identified 23,000 jihahist extremists living in Britain.

British counter-terror chief Mark Rowley said Friday that police had captured "a large part of the network" linked to the bombing.

Live Nation announced Friday that the rock group's May 30 concert at Manchester Arena will not take place.

Rudd said Britain was making good progress with internet companies on this but that more could be done.

The Manchester bomber has been pictured moments before Monday's massacre, as a wave of arrests fuelled hope that further terror threats had been quelled.

But as campaigning resumed in Britain for a snap June 8 election following a halt called after Monday's attack, the issue of security, which had not been widely discussed before the attack, was poised to feature highly.

The opposition Labour Party, emboldened by a rise in opinion polls, argued that Britain's foreign policy had increased the risk of attacks and criticized Conservative Prime Minister Theresa May for cutting spending on policing.

Police also made a further appeal to the public for information to help trace Abedi's activity between his arrival in the United Kingdom and the attack.
