Asjab Uspanov, a native of Chechnya, died hours after being arrested at a Moscow bus stop following the Crocus theater attack on March 22. Chechen opposition channels that have leaked what they claim is his autopsy report that he was beaten to death at the police station.

His case raises concerns about police impunity in Russia after authorities did not condemn the violence used against suspected terrorists during his arrest. The Russian Government has announced a new package of measures to tighten control of immigrants.
