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

The woman, from Haringey in north London, was held at 11.30 GMT after a flight from Istanbul in Turkey.

West Midlands Police said the woman is being questioned at a police station in the West Midlands on suspicion of preparing for acts of terrorism.

The arrest was part of an intelligence-led operation, it added.

There has been concerns over Britons travelling to Iraq and Syria to join Islamic State militants and the UK terror threat level was raised from substantial to severe earlier this year.

The government's Counter-Terrorism and Security Bill was introduced to Parliament last month. It contains a range powers including orders to block suspected fighters from returning to the UK.
