The teenager arrested on suspicion of planting a bomb on the Tube is reportedly an Iraqi orphan who moved over to the UK as a refugee three years ago, a community leader said today.

The 18-year-old was detained by police on Saturday morning in connection with the terror attack, which saw 30 people injured when a home-made bomb was detonated on a packed carriage.

Following the arrest, police raided a house in Sunbury-on-Thames, Surrey – home to foster care couple Penelope and Ronald Jones who have reportedly taken in refugee children in the past.

As police continued to search the property, a local council leader told reporters that he believed the teenage suspect is an Iraqi orphan who moved to Britain aged 15 after his parents died.
