Moscow: A nanny has been arrested after she was seen on the street carrying the severed head of the 4 year old girl who is reported to be under her care in Russia's capital city of Moscow.

The nanny has been identified as Gyulchekhra Bobokulova, 38, from Uzbekistan. The child was a 4 year old girl named Nastya.

"The child's nanny, a citizen of one of the Central Asian states born in 1977, waited for the parents and elder child to leave the flat and then, for reasons not established, murdered the infant, set fire to the flat and left the scene," the Moscow Investigative Committee said in a statement, adding that Bobokulova was placed in psychiatric care as officials investigate if she suffers from mental illness or was under the influence of drugs.

Graphic videos of the incident show the woman, dressed in a hijab, shouting "Allahu Akbar," "I am a terrorist" and "I am your death." The child's decapitated body was found in the apartment in Moscow where a fire was reported.

Bobokulova was arrested after a police officer asked her for identification outside the Oktyabrskoye Polye metro station in northwest Moscow. She pulled the head out of a bag and began screaming that she would detonate herself.
