A man has been arrested at Gatwick Airport over a suspected terrorism offence.
Police detained the 25-year-old suspect at around 4am on Monday morning after he arrived on a flight from Turkey.
He was arrested on "suspicion of possession of material likely to be useful to a terrorist," Scotland Yard's Counter Terrorism command said.
The man remains in custody at a central London police station.
Detectives are searching an address in north London as part of the ongoing investigation.
