A Muslim community worker has told BBC News that members of the public called the police anti-terrorism hotline warning about the Manchester suicide bomber’s extreme and violent views several years ago.
The BBC also understands that Abedi was in Manchester earlier this year when he told people of the value of dying for a cause and made hardline statements about suicide operations and the conflict in Libya.
The community worker – who did not want to be identified – said two people who knew Salman Abedi at college made separate calls to the police.
They had been worried that “he was supporting terrorism” and had expressed the view that “being a suicide bomber was OK.” The friends had argued with him, telling him he was wrong but had become so concerned they contacted the police.
The community worker told the BBC “all of the publicity is about Muslims not coming forward and this shows that they are coming forward and expressing their concerns.”
The calls are thought to have been made around five years ago after Abedi left school, where he was known to have smoked marijuana and mixed with gangs in south Manchester.
Greater Manchester Police said they would not comment on the claims.
Fawzi Haffar, speaking on behalf of Didsbury Mosque, says: "This act of cowardice has no place in our religion...we encourage anyone with information to contact police."
He denies reports that suspected attacker Salman Abedi worked at the mosque.
"Manchester is a great city, with a great history... Manchester Islamic Centre is proud to be part of this great city," he adds.

"If somebody is going off track, it is an obligation of the Muslim community... to report it to the authorities" says a member of the Didsbury Mosque where it is thought the Manchester Arena attack suspect Salman Abedi also attended.
Giving only his first name, Saleem who runs an interfaith group, also told Martha Kearney that the mosque environment promotes peace and community cohesion.
Saleem did not know Salman Abedi but Abedi's father used to do the call to prayer at the mosque.

Defence Secretary Sir Michael Fallon tells the BBC: "At the request of the police we've deployed 980 troops to take over some basic guard duties.
