A 15-YEAR-OLD schoolgirl died after going to bed without telling her parents she'd been stabbed in a mass brawl.
Elizabeth Kindsfater was knifed in the chest in a fight with other teens in the city of Yekaterinburg in the south-western Russian region of Sverdlovsk Oblast.
According to local media the brawl involving three groups of boys and girls resulted in Elizabeth and another boy being stabbed.
The 15-year-old managed to make it home but did not want to tell her parents she had been in a fight.
Her devastated parents found unconscious in her bed later that night and she was rushed to hospital.
Despite the efforts of medics she was pronounced dead shortly after arrival.
Police have since arrested a 16-year-old boy on suspicion of murder.
A police spokesperson said: "For now, we have reason to believe that the schoolgirl was killed because of animosity between the victim and the suspect after she insulted him."
