THE FBI warned the UK’s security chiefs in January that Salman Abedi was plotting a jihadi attack in Britain, it has been reported.
The information is reported to have come from a US investigation into Abedi and his ties to terror groups in Libya.
In 2016, it was alleged that US security services put Abedi on a terror watchlist used by agents to identify key suspects.
The claim is likely to increase pressure on MI5 to reveal how and when it became aware of Abedi.
It also comes at a time where there are questions over why UK spies decided Abedi did not pose a significant threat to British security.
“The information came from the interception of his communications by US federal agents, who had been investigating Abedi since the middle of 2016, and from information unearthed in Libya, where his family was linked to terrorist groups.
“Following this US tip-off, Abedi and other members of the gang were scrutinised by MI5. It was thought at the time that Abedi was planning to assassinate a political figure.
“But nothing came of this investigation and, tragically, he slipped down the pecking order of targets.”
