Two 21 year old men were arrested on their return from Turkey on suspicion of partaking in “terrorist activities” in Syria.
The men, who are both from Birmingham, are believed to have gone to Syria in May last year.
Det Chief Supt Kenny Bell, head of the West Midlands Counter Terrorism Unit, said to media:
"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."
