Manchester attack probe nets another arrest, 14 now in custody

The arrest means 14 men are now in custody in Britain for suspected roles in the bombing of an Ariana Grande concert that killed 22 people.

Greater Manchester Police said the man was arrested in Shoreham-by-Sea on suspicion of terrorism offenses and an address there was being searched.

One person has been arrested in connection with the attack.

"The review will look at what was known about Abedi, what decisions were made about the intelligence and what, if anything, could have been done differently", the source said, speaking on condition of anonymity.

"What we are doing is challenging the people who are delivering end-to-end encryption to work with us so that we have a way of keeping people safe", she said.

It later emerged it was alerted to his extremist views at least three times. BBC Newsnight reported that when Abedi was 16 he fought against the Colonel Gaddafi regime with his father during the school holidays.

Military personnel have also been deployed to protect Britain's key sites after the national terror-threat level was raised to its highest level from severe to "critical", signifying that another attack may be imminent.

Investigators gave details of Abedi's last hours as they released photographs from security cameras showing the black-clad suicide bomber wearing jeans and trainers, a black bodywarmer and baseball cap, the straps of his backpack visible on his shoulders.

British police earlier released a photograph of Abedi on the night of the attack in Manchester and say they believe an apartment in the city centre was where he put together his device.

Prime Minister Theresa May said developments in the investigation into the bombing meant intelligence experts had chose to lower the threat level from its highest rating "critical", meaning an attack could be imminent, to "severe". There was always a lot of coming and going in and out of that building.

They have "just started to be used", she told Sky.

From 2009 to 2016, the number of police officers fell by nearly 20,000, or around 14 per cent, according to the independent Institute for Fiscal Studies think tank.

British authorities say they have disrupted five plots since March 22, when a terror attack outside Parliament in London left five people dead.

Abedi, whose parents come from Libya, is thought to have received terrorist training in the country before returning to the United Kingdom just days before detonating the bomb that killed 22 people.
