A 39-year-old Chinese man savagely slit his young son's throat and then sliced off his genitals after he wet the bed, police said. The incident took place in China's Zhenxiong village.

Tang Minghua was looking after his 9-year-old son Kao alone after his wife walked out. He reportedly freaked out after finding the boy had urinated in his bunk, nydailynews.com reported.

Minghua dragged the youngster out of their home and forced him to empty his bladder, but when the child refused he used a machete to hack at his neck and kill him.

He then allegedly chopped off the dead boy's private parts, before going back to bed.

Cops were called after shocked neighbours spotted the bloody corpse lying outside the home.

Minghua was arrested and charged with murder.

It's unclear exactly when the horrific incident happened. But the boy had reportedly started wetting the bed after becoming upset in the change of family circumstances, the report said.
