The suicide bomber who killed 22 people and injured dozens more in Manchester was identified Tuesday as 22-year-old Salman Abedi, a British-born son of Libyan refugees, police said.

The Manchester United soccer fan — who was born in the city — was named by Chief Constable Ian Hopkins, who declined to provide details about Abedi because the coroner had not formally completed his identification work.

“Our priority, along with the police counter-terrorism network and our security partners, is to continue to establish whether he was acting alone or working as part of a wider network,” Hopkins told reporters.

But details emerged about the practicing Muslim, who local reports said had been known to authorities before the attack, Metro of the UK reported.

Heavily armed police swarmed his semi-detached home on Elsmore Road in Fallowfield, a suburb of Manchester, where neighbors said police set off a controlled explosion, The Sun reported.

After the raid, a forensic officer was seen holding a booklet titled “Know Your Chemicals,” the paper reported.

Police are believed to have recovered surveillance video of Abedi as he walked into Manchester Arena, where he detonated his nail-filled device.

The footage shows that the blast was caused by a crude, homemade bomb contained in a bag, a source told The Guardian.

Neighbor Lina Ahmed, 21, said she saw Abedi chanting loudly in Arabic weeks before the attack.

“He was acting strangely,” she told The Sun. “A couple of months ago he was chanting the first kalma [Islamic prayer] really loudly in the street. He was chanting in Arabic.

“He was saying, ‘There is only one God and the Prophet Mohammed is his messenger,’” she said.

In the past year, he also grew a beard, his school pals said.

Abedi was born in Manchester to Libyan-born parents Samia Tabbal and Ramadan Abedi, a security officer, who emigrated to London before moving to Fallowfield 10 years ago, the Telegraph reported.

He grew up in the Whalley Range area, near a girls’ high school that made headlines in 2015 when twins Zahra and Salma Halane, both aspiring medical students, moved to ISIS-controlled Syria.

Abedi has a brother, Hashem, 20, and sister, Jomana, 18.

Jomana attended Whalley Range High School and worked at Didsbury Mosque in 2013. She said on Facebook that she has many Libyan connections.

Another neighbor, Simon Turner, described the chaotic scene when cops converged on Abedi’s home.

“It was so quick, these cars just pulled up and all these police with guns, dogs, jumped out of the car and said to us, ‘Get in the house now!’” Turner told Metro.

“It was like something from a movie scene. It was unbelievable, really,” he said about the explosion that blew off the front door.

Police also arrested a 23-year-old man elsewhere in connection with the investigation.

MI5 — the UK’s domestic counter-intelligence agency — is investigating Abedi’s possible links to terror cells, The Sun reported.

“Attacks like this are mercifully rare because they require expertise — or a great deal of luck — to pull off,” a source told the paper. “In this case the real fear is that Abedi was just the tip of a more sinister network.

“The focus will now be on his friends, family and other ties to see if there was a sprawling terrorist network behind him,” the source said.

ISIS earlier Tuesday claimed responsibility for the attack without naming the suicide bomber.

“With Allah’s grace and support, a soldier of the Khalifah managed to place explosive devices in the midst of the gatherings of the crusaders in the British City of Manchester, in revenge of Allah’s religion, in an endeavor to terrorize the mushrikin, and in response to their transgressions against the lands of the Muslims,” ISIS said in a statement published by its Amaq news agency.

“Mushrikin” refers to those who do not worship Allah.

“The explosive devices were detonated in the shameless concert arena, resulting in 30 [sic] crusaders being killed and 70 others being wounded,” the statement said. “And what comes next will be more severe on the worshippers of the Cross and their allies, by Allah’s permission. And all praise is due to Allah, Lord of creation.”
