The sister of a Birmingham man arrested on suspicion of terrorism offences relating to Syria told Channel 4 News of her family's fears in July last year, the news programme has claimed.
Channel 4 News claims it knows the identities of both men arrested at Heathrow Airport today, and that the sister of 21-year-old Ali was worried after he left university and told them in a note that he was going to Istanbul.
The woman, who wished to remain anonymous, said at the time: "In the past we have had conversations about Jihad and everything, and he wasn't that extreme that he wanted to go off and do something like that.
"He wanted a purpose, like a sense of belonging, and I think that's what they gave him".
