Russian authorities have formally indicted historian Yury Dmitriyev on a charge of sexual assault against his adopted daughter following an earlier acquittal on child-pornography charges.

The Investigative Committee said on July 3 that Dmitriyev was charged with "violent acts of a sexual nature committed against a person under 14 years of age."
