Police are continuing to question an eighteen-year-old woman who was reported to have travelled to Syria to fight against Isis.

Silhan Ozcelik, 18, from Haringey in north London, was arrested by Met Police counter-terrorism officers on Friday afternoon at Stansted airport on suspicion of preparation of acts of terrorism and membership a proscribed organisation.

Since she travelled to Syria in October last year detectives have been working to establish whether she went to the war-torn country to join the Kurdish YPJ to fight against Isis or to volunteer as a humanitarian worker.

Speaking yesterday afternoon, Ms Ozcelik’s family said they had not been informed by police of her arrest until midday and that she had always wanted to work as an aid worker.

Her mother Ergun said: "We don't know anything. We haven't heard from the police." A male family friend, who declined to be named, said she had not gone to Syria to fight.

The British government is directly arming Kurdish forces but Home Office guidelines says that British citizens taking part in a conflict overseas could be an offence under anti-terrorism laws.

In September, David Cameron said that "highly trained border staff, police and intelligence services" at Britain’s airports would be able to tell the difference between Islamist fighters and those had travelled to the Middle East to combat them.
