The teenager reportedly filmed the murder and sent the video to friends via popular messaging app WeChat. He was arrested several days later after a friend showed the clip to his mother, the BBC reported.
The boy killed his mother after a quarrel at their home in Wenxing town of Sichuan province on Sunday night, reported Radio Free Asia. He then decapitated her and stored her head in a bucket, before disposing it in a drain.
The murder was not discovered until Wednesday, when one of the boy's classmates showed the video clip to a parent who immediately reported it to the police.
The boy was arrested at school.
