MOSCOW : A nanny accused of decapitating a young girl in her care then walking through the street brandishing the head, on Wednesday said "Allah ordered" the killing as she appeared at a Moscow court.

Suspect Gyulchekhra Bobokulova from Muslim-majority Uzbekistan - whom the press have dubbed "the bloody nanny" - was detained on Monday as she was waving the child's severed head outside a metro station in northwestern Moscow. She was sent for psychiatric examinations. "It was what Allah ordered," the 38-year-old told journalists as she was brought into the district court to have her arrest confirmed and extended.

With shoulder-length black hair parted in the centre, she wore a royal blue pinafore over a black tracksuit top. At times, she smiled, other times she grimaced, flashing a few golden teeth. Investigator Olga Lapteva, who was clearly emotional, told the court that Bobokulova was suspected of committing an "extremely serious crime" and that she should face "a mandatory prison sentence of considerably more than three years."

The court confirmed the nanny's arrest and ordered her held in custody for two months as investigations continued.
