Police have arrested a woman at Stansted Airport on suspicion of possessing a terrorist document.

The 41-year-old was stopped by counter-terrorism officers from Scotland Yard after she allegedly attempted to board a flight to Sweden at 5pm today.

Metropolitan Police chiefs said she was then arrested on suspicion of possessing a document likely to be useful for the purposes of terrorism, contrary to Section 58 of the Terrorism Act 2000.

She is being held in custody at a south London police station.
