Born in Manchester to parents of Libyan origin, Abedi is the second youngest of four children.
A Manchester United fan and a keen cricketer, he attended the boys’ school, Burnage Academy.
Today, French interior minister Gerard Collomb said Abedi had “proven” links with the Islamic State terror group.
He also told French television that both British and French intelligence services had information that he had been in Syria.
His comments came as Home Secretary Amber Rudd confirmed UK security services had been aware of the British-born suspect.
The terrorist who killed 22 people by detonating a suicide bomb at Manchester Arena has been named as Salman Abedi.
Born in Manchester in 1994, the 22-year-old bomber was known to the security services and had “proven” links with ISIS.
He is believed to have returned from Libya just days before the terror atrocity, having previously spent time in war-torn Syria.
Hundreds of fans were leaving an Ariana Grande concert at the packed arena on Monday night when Abedi set off the IED.
Nearly two dozen people were killed and a further 119 were injured, with some reportedly losing body parts in the blast.
Many of the gig goers were young female fans of school age, with an eight-year-old schoolgirl among those killed.
Below, we look at the terrorist behind the deadly attack, which occurred as fans walked through the arena’s foyer area after the gig.
“We do know that he was known up to a point to the intelligence services,” she told Sky News.
“I am sure that we will get more information about him over the next few days and the next few weeks.”
Speaking to BBC radio, Rudd said it was likely Abedi did not act alone in the bombing, which shocked the world.
“It seems likely, possible, that he wasn’t doing this on his own so the intelligence services and the police are pursuing their leads in order to make sure they get all the information… that they need to keep us safe,” she said.
When asked if Abedi was known to the intelligence services, she added: “The security services will know a lot of people, it doesn’t mean they are expected to arrest everybody that they know but it is somebody that they had known before and I’m sure when this invetigation concludes we’ll be able to find out more.”
Abedi, who lived in the Fallowfield area of Manchester, spent three weeks in Libya before the attack, The Times reports.
A friend told the newspaper: “He went to Libya three weeks ago and came back recently, like days ago.”
There are claims that, in the hours before the atrocity, he had travelled by train from London to Manchester.
During his childhood, Abedi lived near Whalley Range High School.
It is the same school of twins and formerly aspiring medical students, Zahra and Salma Halane, who left their homes and fled to Syria in 2014.
He is thought to have been a student at Salford University,
Dr Sam Grogan, the university’s Pro-Vice Chancellor Student Experience, said yesterday: “All at the University of Salford are shocked and saddened by the events of last night. Our thoughts are with all those involved, their families and their friends.
