Police make fresh arrest over Manchester bombing

Manchester : British police said they had arrested a new suspect on Monday over the Manchester bombings, bringing to 14 the number of people they have in custody over the attack.

Authorities detained a 23-year-old in the southern coastal town of Shoreham-by-Sea, more than 400 kilometres (250 miles) from Manchester.

In addition, police raided a property in a southern Manchester suburb as they step up their investigation into last week's bombing that killed 22 people.

The attack, Britain's worst in more than a decade, was carried out by British-born extremist Salman Abedi, who detonated a powerful bomb at the exit of a concert by US singer Ariane Grande.

Several of the victims were children, the youngest being just eight. Scores were injured in the attack.

Police have been hunting for a network of people connected to Abedi, with Britain's interior minister Amber Rudd saying on Sunday there were "potentially" still members of the cell at large.

"The operation is still really at full-tilt in a way and so until the operation is complete we can't be entirely sure that it's closed," said Rudd.

Abedi's brother and father are being held in Libya.

On Sunday, police released photographs from security cameras showing Abedi on the night of the massacre, wearing jeans and trainers, a black bodywarmer and a baseball cap, with the straps of his backpack visible on his shoulders. 

Britain has downgraded its security level from its highest level, but it still remains at "severe", meaning an attack is highly likely.
