Suicide bomber who slaughtered 22 'was known to police': Attacker was CAUGHT on CCTV and may have carried out a recce mission to Ariana Grande concert venue
- Police trying to establish who carried out attack at Manchester Arena last night
- Examining whether the suicide bomber was a 'lone wolf' or part of a terror cell
- Terrorist was killed in the blast as he murdered 22 after Ariana Grande concert
- Understood to have arrived at a nearby train station before detonating device
The suicide bomber who slaughtered 22 at Manchester Arena may have been known to police before carrying out last night's atrocity, it has emerged.
An urgent police probe is underway this morning to determine whether the attacker acted alone or had accomplices as part of a wider terror cell.
Officers are also combing CCTV to determine whether he carried out a 'recce' of the arena before detonating a nail bomb as thousands were leaving the
Ariana Grande concert at 10.30pm.
Nobody has claimed responsibility for the explosion, which is being treated as an act of terrorism. But last night,
ISIS supporters were celebrating the massacre online while two messages, posted four hours before the attack, appeared to predict the mass killing.
Concert halls and nightspots have been targeted in the past in ISIS attacks, including in Paris at the Bataclan music venue in 2015 and at the Reina nightclub in Istanbul on New Year's Eve. It is not yet clear why Manchester has been targeted.
The suicide attacker is said to have been 'known' to the authorities and anti-terrorist officers are going through hundreds of hours of CCTV footage trying to 'pick him up' during his journey to the arena.....
