The Met Police say that Counter Terrorism Command (CTC) have arrested three teenage young men on suspicion of preparation of terrorist acts.
Scotland Yard says detectives in CTC were tipped off on Friday that two 17-year-old boys from north-west London had gone missing and were believed to be travelling to Syria.
It’s understood the police were alerted by the parents of the two 17 year old youths.
Police established they’d travelled with a third male aged 19.
Officers alerted the Turkish authorities who were able to intercept all three males, preventing travel to Syria.
Yesterday all three young men returned to the UK and were detained at around ten minutes past eleven at night on suspicion of preparation of terrorist acts contrary to Section 5 of the Terrorism Act 2006.
The Met Police say all three have been taken to a central London police station, where they remain in custody.
The BBC reports that Turkish officials are saying non-attributively that the three young men entered the country from Spain and were intercepted at one of two airports in Istanbul.
It’s reported they were deported by the Turkish authorities.
The Turkish government and police wish to demonstrate their willingness to cooperate with Britain to halt the growing trend of some young British muslim men and women to join the so-called Islamic state in Syria and Iraq.
Keith Vaz, the chair of the House of Commons Home Affairs Select Committee, says this is an example of much better liaison and communication between the British and Turkish authorities.
He said that parents of young people vulnerable to being brain-washed by extremist Islamist propaganda must be as vigilant as they can to help prevent their children being lured to Syria.
We need to be vigilant. Clearly this flight of young people to Turkey in order to go to Syria is on a much larger scale than we envisaged.
