Manchester suicide bomber Salman Abedi was part of a terror network, police said Wednesday afternoon.
Ian Hopkins, head of a Greater Manchester Police, said at a media briefing: "I think it's very clear that this is a network that we are investigating."
He said investigation of Monday's bombing attack, which left 22 dead, the youngest aged just 8, was "continuing at a pace".
"There's extensive investigations going on and activity taking place across Greater Manchester, as we speak," Hopkins said.
