LONDON, Nov. 14 (Xinhua) -- A 26-year-old man was arrested on Thursday on suspicion of "Syria-related" terrorism offences after landing at Heathrow Airport in London on a flight from Turkey.
The man, who has not been named, was arrested by London police's counter-terrorism command. Scotland Yard said that he was held "on suspicion of preparation of terrorist acts under section 5 of the Terrorism Act 2006".
London police said the arrest was "Syria-related". He remains in custody as the investigation continues.
Earlier Thursday, the Turkish Interior Ministry said it had deported eight Islamic State (IS) suspects, including a Briton and seven Germans.
The Turkish ministry did not identify any of the suspects and the British Home Office also refused to disclose any details.
Turkey will send back IS group captives to their countries of origin even if some of the countries have deprived them of their citizenship, Turkish Interior Minister Suleyman Soylu said earlier this month.
The minister also said on Wednesday that Turkey deports the IS members regardless of their original nationality.
Turkey, which started a campaign to send IS members back to their own countries this week, has repeatedly criticized European states for refusing to take back any of the 1,200 foreign IS suspects captured by Turkey.
