Four men have been arrested at Luton Airport by counter-terror police on suspicion of being members of a banned organisation.
The men, all Sri Lankan nationals, arrived on an international flight on Wednesday evening and were arrested the following day.
Scotland Yard has said they are currently being held in custody at a police station in Bedfordshire.
A spokesman said: “Police at the airport were made aware of the men the next day, Thursday 11 April, and subsequently stopped them under schedule seven of the Terrorism Act 2000.”
Inquiries are ongoing.
