The bomber - named today as 22-year-old Salman Abedi - was known to authorities. He died at the scene and police carried out a controlled explosion at what is believed to be his home during raids around the city today.
Abedi is understood to have been born in Britain but is from a Libyan family. A school friend told MailOnline had grown a beard when he last saw him and neighbours claimed he had been ‘acting strangely’ recently.
A 23-year-old man, believed to be Abedi’s brother, was also arrested by anti-terror officers as police and security services attempt to work out if the suicide bomber was part of a cell.
Security sources have told MailOnline that initial analysis of the ‘sophisticated’ device suggests it was made by an expert.
And that's what people don't understand. The problem isn't necessarily the people who come from the other countries. I suspect many are grateful to the host country for allowing them to escape the hell-holes from whence they came. The problem is their offspring, who have no such appreciation, and isolate themselves from the host culture. Those are the ones who wind up being radicalized. And it's only going to get worse over time.
