The suicide bomber who brought carnage to the Manchester Arena has been named as Salman Abedi.

Police confirmed his name after armed officers carried out a dramatic raid on the redbrick semi in south Manchester where the 22-year-old was registered as living.

Greater Manchester Chief Constable Ian Hopkins said detectives were working to establish whether Abedi, whose attack left 22 people dead, including an eight-year-old girl, was working alone.

He said: "I can confirm that the man suspected of carrying out last night's atrocity has been named as 22-year-old Salman Abedi.

"However, he has not yet been formally identified and I wouldn't wish, therefore, to comment further.

"The priority remains to establish whether he was acting alone or as part of a network."

Residents of Elsmore Road in Fallowfield where he lived described being ordered to remain indoors as more than 20 officers, all armed, swooped on the house, carrying out a controlled explosion on the front door.

Elsewhere in south Manchester, the first arrest was made in connection with the inquiry when a 23-year-old man was detained near a Morrisons in Chorlton.
