A 25-year-old woman has been arrested at Luton Airport on suspicion of Syria-related terror offences.

Detectives from the West Midlands counter-terrorism unit detained the suspect as she got off a flight from Istanbul in Turkey.

The woman, from Haringey in north London, was arrested at around 11.30am as part of a continuing intelligence-led policing operation.

She is being held at a police station in the West Midlands on suspicion of preparing for acts of terrorism.

The terror threat level in the UK was raised from substantial to severe earlier this year.

It came after increasing concerns over hundreds of aspiring British jihadis travelling to Iraq and Syria to learn terrorist "tradecraft".
