Mother tells how son became a Jihadi in Somalia
Thomas Evans was brought up in Buckinghamshire, but at the age of 21 he left Britain to join an Islamist terrorist group in Somalia.
In a Channel 4 documentary, his mother Sally and brother Michael explain how Thomas changed from a "happy and funny" boy into a radicalised murderer.
Ahead of the programme's broadcast, they told Victoria Derbyshire how they believe it could happen to other families.
Sally Evans said: "It's not just a Muslim problem, it's everybody's problem."
