A jealous Russian teenager hacked off the head of his love rival, then took it to show his “distraught” girlfriend to prove his love for her, police have said.

The 16-year-old kickboxer is reported to have asked to meet Artyom Shustov, 19, in a park in the eastern Russian city of Komsomolsk-on-Amur, where the pair got into a furious row.

The younger teen accused the older one of forcing himself on his girlfriend, 17, at a party.

Shustov insisted the girl had “started pestering him at the party, and he was drunk and could not resist her,” according to Russian newspapers which cited police sources and witnesses.

The pair began fighting and the younger teen took out a kitchen knife from his backpack and twice stabbed his rival in the back and abdomen, it is claimed.

With Shustov still alive but badly wounded, the younger teen is said to have then “started to cut off his head with the knife.”
