Gulchekhra Bobokulova, a 38-year old mom of three, spoke to reporters on her way.
CCTV appeared to reveal her, dressed in a hijab, walking using a head in her hands near a metro station.
Russian media reported that she pulled the head out of a bag and began shouting that she’d blow up herself after a police officer requested to see her identity documents.
Amateur video posted online revealed a black-clad girl yelling “I ‘m a terrorist. I am your death”.
Investigators told the Presnensky district court they’d not found anyone else associated with the case.
But prosecutors also said they considered that Bobokulova had been “incited” to perpetrate the offense.
