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

One of those arrested is Ismail Abedi, the brother of the suicide bomber, Salman Abedi. The Abedi brothers are UK citizens and both of their parents immigrated from Libya. It is thought that Salman may have traveled to Syria and Libya in the recent past. Since the arrest of Ismail and the identification of Salman as the bomber, their father has protested their innocence.
