During the most recent press conference, Manchester police chief Ian Hopkins stated that they have arrested four people so far during their investigation of the bombing of the Manchester arena and the evidence suggests a terror network was responsible for the terrorist attack. Islamic State did claim responsibility for the attack several hours after the bombing which killed 22 and injured 64.

I think it’s very clear that this is a network that we are investigating,” Hopkins told reporters outside Manchester police headquarters.

“And as I’ve said, it continues at a pace. There’s extensive investigations going on and activity taking place across Greater Manchester as we speak.”- Reuters
