Police have arrested a second refugee foster child who had been living with the same family as part of the terror investigation into the Parsons Green bombing.

Yahyah Farroukh, 21, was arrested outside the chicken shop where he worked in Hounslow on Saturday night just hours after police caught the 18-year-old suspected of planting the Tube bomb at the Port of Dover, witnesses say.

After his arrest police cordoned off his home just yards from Heathrow Airport in Stanwell, Surrey. The Syrian refugee had previously lived at the home of Ron and Penny Jones, who had been fostering the 18-year-old before his arrest.

Officers also searched Aladdins Fried Chicken in Hounslow.
