The suicide bomber who detonated deadly blasts at Ariana Grande's Manchester concert has been named as 22-year-old Salman Abedi.
Police confirmed the identity of the man after officials in the United States passed it to news reporters.
Albedi, of Libyan descent, murdered 22 people have injured 59.
He was reportedly known to the security services but was not regarded as a high risk.
The Telegraph report that he had been "radicalised recently".
The Islamic State have claimed responsibility for the attack, however police have not found any evidence to support this, and are still working to discover whether Abedi worked alone or not.
