A man has been arrested in connection with the investigation into the attack at Manchester Arena.
The 19-year-old man was arrested at Liverpool John Lennon Airport today.
He was arrested on suspicion of offences contrary to the Terrorism Act and remains in custody.
A property on Thelwall Avenue in Fallowfield is being searched as part of the investigation.
Detective Chief Superintendent Russ Jackson, head of the North West Counter Terrorism Unit (NWCTU), said on Thursday that while detectives do not now think Abedi was part of a large network, they do suspect the involvement of others in the attack and hinted that further arrests were possible.
As it stands 23 people have now been arrested in connection with this investigation, of which two were quickly de-arrested, and 20 were released without charge.
One person remains in custody.
