FOSTER parents in Cumbria need to be told if they take on a child who has a radicalised background, Barrow’s mayor has warned.

Cllr Bill McEwan has raised the case of Parsons Green bomber Ahmed Hassan who was fostered by a Surrey couple as a young Iraqi asylum seeker.

Hassan’s foster parents are now suing Surrey County Council because they claim they were never told he admitted to social workers that he was “trained to kill by Isis”.

In a BBC interview last week, his foster parents said: “If we had known he was a trained killer he wouldn’t have got over the doorstep.”

Hassan, whose age remains in doubt, is serving a life sentence after his homemade bomb partially detonated on a London tube train in 2017.

The device – packed with screwdrivers, knives and nuts and bolts – sent a fireball through a packed carriage – injuring 50 people.

At a meeting with county council officials in Barrow, Cllr McEwan has raised the issue of how much foster parents are told about those they take on.

It followed a discussion at Barrow’s Local Committee about the Home Office Syrian refugee settlement programme.

Cllr McEwan, the Labour councillor for Ormsgill, asked for reassurances that foster parents are fully informed of the background.

He said: “The couple fostered him and he tried to blow up a train yet the authorities knew that he was a trained killer because he had told them.

“This couple took him in having fostered children for 30-odd years and were not informed. Does Cumbria County Council inform people what the background of these people are?”

Jonathan Taylor, a senior manager for Cumbria County Council, replied that the process of fostering was “very robust”.

Mr Taylor said: “We don’t just a place a young person, we do a whole matching process. We would go through a whole process in terms of matching to make sure all that information is shared. The foster parents need to make an informed judgement of whether they are happy to manage that risk.”

Cllr McEwan, the chairman of the Cumbria Police and Crime Panel, said it was important that foster carers were told the truth.

He said: “Fortunately nobody was killed, but his foster parents didn’t know his background, but the authorities knew. I wouldn’t like that to happen here.”

Lawyers acting on for the foster parents claimed they were told that he was “a very vulnerable young person” who had been “deeply traumatised” by his life in Iraq.

Surrey County Council has contested the claim and has insisted it shared information about the risks from the outset.
