A teenage boy has admitted to killing his ten-year-old sister in her sleep after they argued over using a computer tablet according to local press in Russia.

The girl, named as Luda and described by local media as smart and spirited, was hammered to death at her home in the city of Taraz, northern Kazakhstan in Russia.

She was found with a broken skull and died from horrific injuries before paramedics arrived at the scene.

According to the neighbours, the tragedy occurred after Luda and her brother Aleksey, 15, had a row in the courtyard near their house.

“I heard them quarreling over a tablet and saw Aleksey carrying a hammer in his hand. The girl’s head was crushed. A part of the skull fell off when paramedics lifted up her head.” A neighbour who witnessed the incident narrated

Aleksey is said to be a gamer and his sister had asked for the device for studying. Aleksey attacked Luda at night in her sleep by smashing a hammer into her head multiple times.
