Manchester attack: An operation that puts pressure on security services

Security sources are also concerned about the prospect of jihadists returning from Iraq and Syria

Greater Manchester Police force has confirmed that the explosion in the foyer of Manchester Arena on May 22 is being treated as a “terrorist incident”.

And while the force’s chief constable Ian Hopkins said the attack was carried out by a single individual; he added that the focus of the investigation was to establish whether the individual was acting alone or as part of a network. Hopkins said:

The attacker, I can confirm, died at The Arena. We believe the attacker was carrying an improvised explosive device which he detonated causing this atrocity.

A 23-year-old man has since been arrested
