Greater Manchester Police's suspect for yesterday's attack, Salman Abedi, was born in Manchester and was 22 years old.
He has at least three siblings: an elder brother who was born in London, and a younger brother and sister who were born in Manchester.
The family is believed to be of Libyan origin.
They have lived at more than one address in Manchester, including the property at Elsmore Road in the Fallowfield area that was raided by police today.
Neighbours described how the family would fly Libyan flags at some times of year.
