A man has been arrested at London’s busiest airport on suspicion of terrorist offences relating to Syria.
The 26-year-old man was arrested on Thursday after arriving at Heathrow airport on an inbound flight to the UK from Turkey, the London Metropolitan Police said.
He was arrested on suspicion of preparation of terrorist acts under section 5 of the Terrorism Act 2006.
He currently remains in police custody as enquiries continue, police said.
Earlier this month, Britain reduced its terrorism threat assessment to the lowest level for more than five years.
The threat level was reduced to its third-highest grade, substantial, from severe following “positive developments”, according to the country’s most senior counter-terrorist police officer.
It was raised following a wave of ISIS-inspired attacks on Europe.
