The horrific incident happened in India after Mohammad Abdul Qayyum Qureshi warned his son over constantly watching pornography on his smart phone.
The man had previously told his son that he wanted him to stop watching the blue movies, but the 19-year-old persisted and an argument erupted, the report added.
The young man left the family home, but later returned and the argument continued. The argument grew so fierce that the son bit his father’s hand.
The father, who works as a butcher, pulled out one of his knives and chopped his son’s hand off, he then presented himself to local police.
Now police have said they want to charge the man with attempted murder.
