The Russian police on Monday detained a woman on suspicion of murder after she was found holding the severed head of a child outside a metro station in Moscow. Local media reports said she brandished the child’s head and chanted a religious slogan at the police when officers tried to check her papers. The Russian Investigative Committee said in a statement that the woman was the four-year-old victim’s babysitter, adding that she waited till her parents left the apartment before killing her and setting the place on fire, The Telegraph reported.

Footage of the woman carrying the severed head surfaced online soon after the police found the body of a headless child in an apartment near the metro station, following reports of a fire. The woman has been placed in psychiatric care to determine whether she is capable of understanding her actions, the investigative committee said. The woman was identified as Gyulchekhra Bobokulova, a 39-year-old from Uzbekistan, according to a report by Russian tabloid LifeNews. When approached by the police, Bobokulova threatened to blow herself up, but was found to not have any explosives on her.
