Det første billede af den mistænkte selvmordsbomber, Salman Abedi. Han skal have fået jihad-træning i Syrien, og flere gange rejst til Libyen, hvor hans familie stammer fra.

Politifolk afslørede mandens identitet efter at have gennemført en razzia i hans huset i Manchester tirsdag, skriver The Sun.

Den britiskfødte 22-årige som dræbte 22, mange af dem børn, og sårede 59 andre med en spikerbombe ved Manchester Arena, blev identificeret med billede lige efter, at statsminister Theresa May sent tirsdag aften hævede trusselniveauet til «kritisk» – det højeste niveau.

Det er ti år siden trusselniveauet senest blev sat så højt. Soldater kan blive mobiliseret for at bistå politiet. Faren for et nyt terrorangreb er overhængende.

The Sun can reveal Abedi had secret jihadi training during family trips to Syria and spooks fear he was not acting alone when he carried out the atrocity that ISIS has claimed responsibility for.

But Abedi’s family hail from Libya and he is thought to have visited the North African country – also a haven for ISIS fighters – regularly in recent years.

Sources said there were fears Abedi may have taken advantage of the conflict to make the simple journey across the Med to Syria without alerting the British authorities.

En af The Suns kilder siger følgende: “His potential ties to Syria now very much forms one line of inquiry.”

Cops are also probing whether Abedi, who is believed to have been known to MI5, acted alone or as part of a larger extremist network to carry out the worst terror attack Britain has seen since the 7/7 London bombings.

Met Police Assistant Commissioner Mark Rowley admitted there were “gaps in our knowledge” about Abedi and the PM said it was possible a “wider group of individuals” could have been involved in the “cowardly” attack.
