The apparent obsession of a man to still mentor a 15-year-old boy who used to be his stepson has landed him in trouble after he pleaded guilty to slapping the boy in his face during an argument.

He is Wesley Wallace who has been charged with assault occasioning bodily harm.

Wallace was fined $15,000 or six months in the Corporate Area Resident Magistrate's Court yesterday.

It is reported that the complainant used to live with the accused, however, the death of the complainant's mother in 2010 caused him to leave.

It is reported that on the day of the incident, the accused visited the complainant's school and started arguing with him.

"I was to pick up something from his school on the day of the incident and out of ignorance, I boxed him during an argument. We were arguing about a phone. Your Honour, I have been feeding and clothing him for years, it was just ignorance," the accused told the court.

However, the complainant told the court that the accused boxed him because he wasn't hearing from him, "I live with him for one year and seven months and eventually I told him that I am not coming back. He came to my school one day and started to beat me. He boxed me in my face saying that he has not been hearing from me," the complainant told the court.

Meanwhile, the complainant's aunt who accompanied him to court told Senior Resident Magistrate Judith Pusey that the complainant is now living with her and she has already communicated that to the accused.
