Interpol is reportedly issuing a so-called red notice for Anne Sacoolas, the American woman who killed a British teen in a car crash and then used a claim of diplomatic immunity to return to the United States. U.K. officials have since asked for Sacoolas, whose husband worked at a CIA spy base in Britain, to be extradited and face a charge of causing Harry Dunn’s death by dangerous driving last August. Radd Seiger, a lawyer for Dunn’s family, told The Guardian that a notice means Sacoolas would be arrested if she sought to leave the United States, although Interpol cannot force police to arrest someone.
