An angry father in India allegedly chopped off his 19-year-old son’s hand because the boy would not stop watching porn on his cellphone. Following the heinous maiming, the father has been arrested.

Newsweek reports: Police in Hyderbad said that 45-year-old butcher Mohammed Qayyum Qureshi surrendered to police in the Pahadishareef area, saying he had severed his son Mohammed Khalid Qureshi’s right hand, the Hindustan Times reported.

The son, who works with a local cable company, had recently purchased a smartphone and become addicted to watching films and pornography on the device, police told local media, something the family worried was affecting other areas of his life. It also enraged the older Mohammed who was said to have repeatedly warned his oldest son over the behavior.

Things came to a head on Sunday, police said, when the son was caught in the act of watching pornography, leading to a heated confrontation with his father that culminated in the 19-year-old saying he would be leaving the family home.

On Monday morning,  the argument began again. “In a fit of anger, Qayuum picked up the butcher’s knife and chopped off Khalid’s right hand,” police wrote.

Doctors reportedly said the hand was 90 percent severed but there was a slim chance they could save it.

Times Now India reported that the father of four now faces an attempted murder charge.
