Police arrest 14th man in Manchester bombing inquiry
Police and security services have said very little about the network believed to be behind suicide bomber Salman Abedi, a Manchester native whose parents had moved to Britain from Libya.
Britain's intelligence services have launched an inquiry into how warnings about the 22-year-old Abedi's radical views were handled amid indications that vital warning signs were missed.
Police are scouring 12,960 hours of closed circuit TV recordings in their search for clues, have collected more than 630 pieces of evidence and have searched 21 addresses.
