A horrifying video emerged online showing a 10-year-old boy putting his elderly grandmother in a chokehold and strangling her to death after she punished him by spanking him with a slipper.

The incident happened in Lalatun, Haicheng Town, Zhaodong City.

The grandmother was seen in the video smacking the boy in the head as the boy attempted to snatch a wooden stick from her, before punching his grandmother in the chest.

The elderly woman then reached down to grab a sandal, and the boy then wrapped his arms around his grandmother’s neck and dragged her down onto the floor.

He then maintained his strangling chokehold on the elderly woman, who was desperately trying to free herself from the boy.

Grandma became limp but boy kept strangling her

The boy continued strangling his grandmother, as she eventually stopped resisting and became limp on the floor – the boy still didn’t release his chokehold on his dying grandmother.

The boy was seen shouting in the video “you are always hitting me and saying I’m not being reasonable, so who is the one being unreasonable now?”

The cameraman who was filming, soon realised that the elderly grandmother was not moving anymore, and hurriedly rushed over to pull the boy away from her as he assured the boy that “grandma is not hitting you anymore, you are crushing her to death”.

The boy then released his grip of his grandmother, who remained lying on the ground unmoving, as another middle-aged woman then entered the room and started caning the boy.

The woman then told the boy that grandma was dead as she caned him, and asked him to look at what he’s done.

The boy was purportedly egged on by his friends to get physical and violent with his grandmother before the incident, and they were all arrested by the police following her death.
