Monday 22's attack outside
an Ariana Grande concert at Manchester Arena killed at least 22
people, including children, and was carried out by a lone suspect
carrying a bomb, Manchester Police 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," said Chief Constable Ian Hopkins.
While police believe the
suspect was acting alone, investigations are ongoing to establish if
he was part of a network.
As many as 400 police were
deployed overnight, Hopkins said early Tuesday. He added that
residents should expect to see more armed officers on the streets.
Social media posts from
the scene showed panicked concertgoers running down the arena's
stairs in an attempt to get away.
