Two Russian men, one of them a butcher, have been arrested on suspicion of killing, cooking and eating a 16-year-old girl in St Petersburg.
Prosecutors said that the girl disappeared while on her way to school on Jan 19. She was killed that night and then body parts believed to be hers were later found in plastic bags scattered around the city.
Police arrested Yuri Mozhnov, a florist, and Maxim Golovatskhikh, a street-market butcher and one-time psychiatric patient. Prosecutors believe they drowned the girl in a bathtub, cut her body into pieces and ate some of her internal organs in an act of cannibalism.
"The arrestees said they ate the girl's body parts because they were hungry," said Sergei Kapitonov, a spokesman for the city's prosecutors.
He said that the accused told investigators that they baked some of her insides with potatoes in a stove, he said.
They allegedly then bagged up her remains and disposed of them. He said that both men are being held on suspicion of murder.
The suspects, both 19, knew the victim, and she accompanied them voluntarily to an apartment rented by another acquaintance on the day she went missing, Mr Kapitonov said.
They were arrested on Saturday, a day after plastic bags - one containing a girl's head and others holding other body parts - were found in at least two separate locations.
The St Petersburg news website fontanka.ru cited a top city prosecutor, Andrei Lavrenko, as saying investigators believe the suspects decided to kill the victim after an argument erupted between the girl and Mr Golovatskikh.
