The two men from Birmingham arrested on suspicion of terrorism offences relating to activities in Syria did not pose any imminent threat to the public, the West Midlands Counter Terrorism Unit chief said.
Detective Chief Supt Kenny Bell said following the men's arrest at Heathrow Airport:
We took action this afternoon in order to ensure we can properly understand what activities these men have been engaged in whilst in Syria, not because they posed any imminent threat to the public.
