TWO 16-year-old girls are suspected of murdering and torturing their best friend because she was "too attractive”.

The disfigured body of Viktoria (Vika) Averina, 17, was found at an abandoned building site after she had been tortured, strangled and ripped apart with pieces of broken glass.

Police believe she was “cruelly tortured” before she was strangled to death in the Russian city of Arkhangelsk.

Her face had been ripped with pieces of broken glass.

Police initially believed a male “maniac” was behind the brutal killing but now two former school classmates, both 16, have been detained on suspicion of murder.

The pair, named only by first names Lina and Irina, have allegedly confessed to killing a girl who was seen as their “longtime close friend”, according to law enforcement.

A state investigator said: “According to the young girls, the victim thought she was more beautiful than her friends.

“During the police interrogation, the girls explained that the victim allegedly abused them because of this.

“They did not like such behaviour.”

The girls said Vika - who was studying at college as a chef - was “arrogant because of her bright and attractive face”.

The investigator said: “All three girls are from socially normal families.”

The two suspects had used a fake pretext to persuade Vika to come to a building site where they attacked her, a statement from the Archangel regional investigative committee read.

One of the alleged killers held Vika while the other "passed her objects with which they hit the victim”, it is alleged.

They “broke a bottle against the head of the victim” and “cut her face with smashed glass, and then strangled the victim”.

They went back home after the murder and expressed "horror" when her body was discovered, it is alleged.

A friend told local media that the three were close but that Vika’s friends were “physically bigger than her and behaved like a mob”

She said: “Vika was a beautiful girl but we would never think this was a reason for murder.”

Reports also said that shortly before she was killed, Vika had texted a friend asking her to top up her mobile because she wanted to urgently call her mother and didn’t have enough money on her phone.

The girls had been at school together but Vika had left to start a college course as a trainee chef.

The two young suspects face up to 15 years in jail if convicted.
