A man has been arrested in connection with the Manchester Arena terror attack.

The 19-year-old man was arrested at Liverpool John Lennon Airport on Friday on suspicion of offences contrary to the Terrorism Act and remains in custody, Greater Manchester Police said.

A property in Fallowfield is being searched as part of the investigation.

Police said, as it stands, 23 people have been arrested in connection with the investigation, of which two were quickly de-arrested, and 20 were released without charge.

Anti-terror officers have already said police suspect suicide bomber Salman Abedi did not act alone and detectives want to speak to his brother in Libya.
