The police have named the Manchester Arena suicide bomber, who killed 22 people and injured dozens more, as 22-year-old Salman Abedi of Libyan origins.
Born in Manchester in 1994, Abedi was the second youngest of four children and his parents were Libyan refugees who came to the UK to escape the Qaddafi regime, British media reported. Abedi had two brothers and a sister, who is now 18-years-old.
Britain's interior minister said on Wednesday she believed the suicide bomber had recently returned from Libya.
Asked to confirm whether Salman Abedi had recently come back from the country, Amber Rudd told BBC Television: "Yes, I believe that has been confirmed. When this operation is over, we will want to look at his background and what happened, how he became radicalised and what support he might have been given," she said.
Rudd said up to 3,800 military personnel would be deployed on Britain's streets in response to the worst militant attack for over a decade.
Daesh claimed responsibility for the Monday night carnage, but a top American intelligence official said the claim could not be verified.
Meanwhile British police raided two sites in the northern English city, setting off a controlled explosion in one, and arrested a 23-year-old man in a third location there.
British Prime Minister Theresa May and police said Abedi died in the attack on Manchester Arena - something that went unmentioned in the Daesh claim, which also had discrepancies with the events described by British officials.
British election rolls listed Abedi as living at a modest red brick semi-detached house in a mixed suburb of Manchester where police performed a controlled explosion Tuesday afternoon.
