A man has been arrested at Luton Airport on suspicion of Syria-related terrorism offences.
The 32-year-old was detained by Metropolitan Police counter-terror officers on Thursday evening after arriving at the Bedfordshire airport on an inbound flight.
The force said he was arrested on suspicion of preparation of terrorist acts, contrary to Section 5 of the Terrorism Act.
He was taken to a police station in the Bedfordshire area, where he remains in custody.
“The arrest is Syria-related and not related to any offences at the airport,” a spokesman said.
